Photolysis of 3-tert-butyl-3-chlorodiazirine produces 2-chloro-3-methyl-but-2-ene and 2,2-dimethyl-1-chlorocyclopropane; the former stems from 1,2-methyl migration and nitrogen loss in the excited state diazirine, whilst the latter is a product of 1,3-CH insertion in the tert-butylchlorocarbene derived from the diazirine.
This invention concerns N-(ortho phenylaminoaryl), N′-alkyl sulfamides which are inhibitors of MEK and are useful in the treatment of cancer and other hyperproliferative diseases.

C60 acts as a mechanistic probe for the formation of carbene and for the rearranged product via the excited state in the photolysis of 3-t-butyl-3-chlorodiazirine.

Reactions of arc-generated carbon atoms with acylchlorides proceed by two distinct mechanistic pathways depending on the nature of the alkyl group in the substrate. Acetyl chloride affords vinyl chloride from the putative chloromethylcarbene produced by deoxygenation, whereas pivaloyl chloride gives t-butyl chloride as the predominant product via a chain reaction from the initially generated pivaloyl
