Abstract: | Cyclopropyltriphenylphosphonium bromide (2a) was conveniently prepared from 3-bromopropyltriphenylphosphonium bromide (1a). The Wittig reaction of cyclopropyltriphenylphosphonium bromide (2a) with carbonyl compounds gave alkylidenecyclopropanes (4, 6 and 7). Successive treatment of 1a with two equivalents of base and carbonyl compounds gave alkylidenecyclopropanes (4 and 5) without isolation of intermediary 2a. 2-Methylcyclopropyltriphenylphosphonium bromide (2b) was prepared and allowed to react with carbonyl compounds. |
