Aromatic trifluoromethyldenitration and trifluoromethyldecyanation using trifluoromethyltrimethylsilane

Activation of trifluoromethyltrimethylsilane by potassium fluoride in N,N-dimethylacetamide provides a powerful source of trifluoromethide which is capable of substituting aromatic nitro and cyano groups under nucleophilic conditions, albeit in low yield. The trifluoromethide generated in this system is also a potent base which leads to a number of interesting side reactions via deprotonation of the substrate.

Electron-donating Behaviour of Aliphatic Carboxylic Acids in the Photoreaction with 1,2,4,5-Tetracyanobenzene

Irradiation of an acetonitrile solution of 1,2,4,5-tetracyanobenzene with aliphatic carboxylic acids gives 2,4,5-tricyanoalkylbenzenes efficiently; electron transfer from the carboxylic acids to the excited tetracyanobenzene is essential.
