Green Synthesis of Fluorinated Arenes, Benzoxazinones and Benzamides Three different types of reactions (Suzuki-Miyaura reaction, carbonylation reaction and oxidation reaction) were employed to synthesize an assortment of diverse aromatic and heterocyclic compounds. Fluorinated heterocycles are frequently found in pharmaceuticals, drug candidates, ligands for transition metal catalysts and other molecular functional materials, so efficient methods for the synthesis of these compounds are of significant value. We described a selective strategy for the synthesis of poly-substituted pyridines. The Suzuki-Miyaura reaction of 2,6-dichloro-3-(trifluoromethyl)pyridine with one equivalent of aryl boronic acids resulted in site-selective formation of 2-aryl-6-chloro- 3-(trifluoromethyl)pyridine. Due to electronic reasons, the reaction takes place at the sterically more hindered position. The reactions proceeded smoothly in the absence of phosphine ligands. A general and convenient methodology for 2-amino benzoxazinones synthesis has been developed. Radially available 2-bromoanilines and isocyanates were used as substrates and diverse products have been prepared in good yields. Notably, Mo(CO)6 as a solid CO source was applied instead of gas. x A general procedure for oxidation of both benzyl alcohols and alkyl alcohols to primary amides under catalyst free conditions has been developed. More than 25 examples of primary amides were produced from their corresponding alcohols in moderate to excellent yields. This is a practical procedure for primary amides synthesis, water and tert-butanol are the only by-products.

فضا ابن فیضی

فضاؔ ابن فیضی مرحوم
۱۷؍ جنوری کی شام لکھنو میں تھا کہ مؤ سے ڈاکٹر شکیل اعظمی نے فضا ابن فیضی کے انتقال کی خبر دی ، طبیعت ادہر عرصے سے ناساز ہی رہتی تھی، آخر بے قراری کو قرار آہی گیا اور ایک ایسا شاعر اس دنیا سے رخصت ہوگیاجس کی خوش کلامی اور خوش فکری عصائے دست غزل کا وقار رکھتی تھی۔
وہ خطہ اعظم گڑھ کی مردم خیز سرزمین مؤ میں یکم جولائی ۱۹۲۳؁ء میں پیدا ہوئے، گھرانہ علمی اور ذی عزت تھا، جدامجد مولانا محمد علی فیضی نامور عالم دین اور متعدد مذہبی کتابوں کے مصنف تھے، عربی، اردو اور فارسی میں یکساں قدرت کے ساتھ شعر کہتے تھے، دادا کی یہ میراث فضا کو بھی ملی اور انہوں نے تحدیث نعمت کے طور پر اور عربی رواج کے طرز پر والد کے بجائے داد اسے نسبت کو ترجیح دی، خالص عربی اور دینی تعلیم سے آراستہ فضا نے تجارت اور ملازمت کے ساتھ مشق سخن جاری رکھی، یہ محض طبیعت کا طرفہ تماشانہ تھا، طبیعت میں خودداری اور احساس کی شدت نے دنیا اور زمانے کے درد و کرب کا حساب کرنا سکھایا، ان کی شاعری کی اٹھان اسی لیے غضب کی رہی کہ خارجی زندگی کے مظاہر پر ان کی نظر، حقیقت کے متنوع پہلووں کو سمیٹ لینے والی تھی، ان جیسے اور ان سے پہلے کے اور ہم وطن شاعر خلیل الرحمان اعظمی نے اسی خاصیت کو بیان بھی کر ڈالا۔
فضا کی زودگوئی مشہور ہے، سفینہ زرگل، شعلہ نیم سوز، دریچہ سیم سمن، پس دیوار حرف، سبزہ معنی بیگانہ اور حمد و نعت کا مجموعہ سرشاخ طوبی کے ہزاروں اشعار، اس شہرت کی تائید کرتے ہیں، ان کے علاوہ غزال مشک گزیدہ، لوح آشوب آگہی اور آئینہ نقش صدا کے نام بھی ملتے ہیں، زود گوئی کا لازمی نتیجہ...

یورپ میں قرآن کریم کی طباعت اور تراجم کے مختلف ادوار

After Second World War, when the distances between the East and the West began to reduce and the west paid attention to the eastern knowledge seriously. Especially European countries took interests in Islamic subjects and a new trend was generated which is known as Orientalism and the people who acquire the subjective knowledge are being called orientalists. In this connection the orientalists started shown keen interest in learning Islamic subjects and with that interest their object was not to spread the religion Islam but to negate and cancel the true picture of true religion Islam, fear of dominancy of Islam, spread of Christianity and multiple political nations. That is why the first thing they have targeted was the Holy Quran. While X-Prime minister William Evart Gladstone quoted 1882 ''Till the Quran exists, it is impossible for Europe to down the East''. Since then the new era of publication and translations of Quran took place, in which era the treatise and conversion made in various languages differently in different countries which will be discussed in this research article along with the discussion of orientalists who took part in the compositionor translation.  

پاکستان ٹیلیویژن کے سلسلہ وار اردو ڈرامے میں پنجاب اور سندھ کے جاگیردارانہ سماج کا تحقیقی وتجزیاتی مطالعہ

Drama is among one of the earlier forms of literature. Drama is a medium that has been used to represent cultural and Social realities Since its earliest days. This representation became more evident in the form of television drama. East India company's arrival in the sub-continent brought stage in India and drama started to presented on stage. Theatrical companies started putting on performances for verging audiences. Drama became even more popular with the advent of television. Radio and stage failed to complete with the popularity of television drama. This research (and Thesis) is about those television plays which are based on the feudal societies of Punjab and Sindh. As it would have made the discussion extremely lengthy to include plays from all the centers of Pakistan television, plays from Islamabad, Karachi and Lahore centers taken for the research. The first chapter introduces the topic of the thesis. The basics and principles of drama, its literary impotence, it beginning and evolution, its kinds and traditions are discussed. The second chapter is discusses the feudal system. The reasons of its strength are explanation. How it began and ended in Europe? Why has it survived in Pakistan while being eradicated from the rest of the world? Answers to all such questions are provided in this chapter. Details of when and how PTV transmissions began are furnished as well. From its onset till the twenty first century, feudal system has been a theme of PTV drama repeatedly. Third, fourth and fifth chapters present a critical review of the plays about this system in the light of Pakistan's political and social situation. The last chapter puts forward the marrow of the entire research as it provider an overall analysis of these plays and advances the outcome and recommendations in this regard.
