Katha Pollitt (born 1949), American feminist writer Tetramethylsuccinonitrile or TMSN is an organic compound with the formula (C(CH3)2CN)2.

Some common solvents include acetone, methanol, tetrahydrofuran, dimethylsulfoxide, and water among countless others.

Trimethylsilyldiazomethane may be prepared by treating (trimethylsilyl)methylmagnesium chloride with diphenyl phosphorazidate.

Trimethylsilyldiazomethane is highly toxic.

Inhalation of diazomethane is known to cause pulmonary edema; trimethylsilyldiazomethane is suspected to behave similarly.

A similar hydrolysis reaction may take place when trimethylsilyldiazomethane comes into contact with water on the surface of a human lung.

Organizations based in Tripoli The TASF reagent or tris(dimethylamino)sulfonium difluorotrimethylsilicate is a reagent in organic chemistry with structural formula [((CH3)2N)3S]+[F2Si(CH3)3]−.

He denounced unnecessary and radical surgical procedures and dangerous medications, reminding his readers of public health failures such as the 1976 swine flu outbreak and the damage caused to daughters of women who took the drug Diethylstilbestrol during pregnancy.

A tandem epoxidation with meta-chloroperbenzoic acid and Lewis acid-catalyzed Grob fragmentation gave ketone 6, which was then protected as the tert-butyldimethylsilyl ether 7 in 94% yield over three steps.

The acetyl group was replaced by a tert-butyldimethylsilyl protecting group.

The subsequent development of (dimethyloxosulfaniumyl)methanide, (CH3)2SOCH2 and (dimethylsulfaniumyl)methanide, (CH3)2SCH2 (known as Corey–Chaykovsky reagents) by Corey and Chaykovsky as efficient methylene-transfer reagents established the reaction as a part of the organic canon.
