Studies on Organic Fluorine Compounds. VII. Trifluoromethylation of Aromatic Compounds

Thermochemistry of Organic Fluorine Compounds and Carbon Compounds

Rotating-bomb calorimetry was first applied to organic compounds that contain chlorine, bromine, or sulphur. Techniques developed for these classes of compounds, mostly at the University of Lund and at the Bureau of Mines in Bartlesville, have been described in the book Experimental Thermochemistry-, The development of rotating-bomb methods made accurate combustion calorimetry feasible for othe...

Determination of fluorine in organic compounds.

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...

Perspectives on polyhalogenated aromatic compounds.

Mechanisms of bone invasion by squamous carcinomas of the head and neck have, been investigated using fresh tumours and established tumour cell lines in an in vitro bone resorption assay with 45Ca-labelled mouse calvaria. Fresh tumours regularly resorb bone in vitro. Activity is consistently reduced by indomethacin. The tumours release E2 prostaglandins (PGE2) in amounts sufficient to account f...

Possible mechanism of liver necrosis caused by aromatic organic compounds.

Treatment of rats with phenobarbital, which stimulates the activity of the drug-metabolizing enzymes in the liver, potentiates hepatic necrosis elicited by bromobenzene and a number of other chemically inert halogenated aromatic hydrocarbons. Radioautographic studies indicate that [(14)C]bromobenzene is covalently bound at the sites of necrosis. From these results, it is inferred that the hepat...
