Insertion of P(CN)3 and As(CN)3 as their isonitrile forms into the dimer of hexafluorothioacetone
Abstract
Reaction of 2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithietane with P(CN)3 and As(CN)3 yields stable insertion products, in which the nitriles are rearranged to the corresponding isonitrile structures.
