- HIGH PRESSURE APPROACH TO THE SYNTHESIS OF 7-PHOSPHANORBORNADIENES FORM λ5-PHOSPHOLE OXIDES AND DIALKYL ACETYLENEDICARBOXYLATES
-
Reactions of 1,2,3,4,5-pentaphenylphosphole oxide (4a) with dimethyl and di-t-butyl acetylenedicarboxylates (5a, b) under high pressure afford the tetraphenylphthalates (7a, b) along with the 7-phosphanorbornadiene derivatives (6a, b).The latter adducts h
