Abstract
Abstractβ-Cyanovinyl-triphenylphosphonium bromide (1) rearranges to (2-cyano-1-phenylethyl)diphenylphosphine oxide (2) on treatment with alkali.1 reacts with NaN3 to 5-triphenyl-phosphonium-1.2.3-triazole-ylide (3) and with cyclopentadiene to (5-cyano-bicyclo[2.2.1]hepten-2-yl-6)triphenylphosphonium bromide (4). Reaction of1 with thioamides leads to (α-cyano-β-amino-β-alkyl)-allyl-triphenylphosphonium hromides (6) together with [(2-alkyl-4-aminothiazolyl)-5-methyl]triphenylphosphonium bromides (5). (2-amino-3-imidazo[1.2—α]pyridinyl) methyl]triphenylphosphonium bromide (7) results from reaction of1 with 2-aminopyridine, [(2-amino-3-imidazo[1.2—α]pyrimidinyl)methyl]triphenylphosphonium bromides (8 and9) from 2-aminopyrimidine and 2-amino-4-6-dimethylpyrimidine resp.
