摘要

Abstract A novel synthesis of 1, 3-dioxoles (6a),(6b) and (7a-d) by the action of diphenylmethylenetriphenylphosphorane (1) and fluorenylidenetriphenylphosphoranes (2) on tetrahalo-o-benzoquinones (5) is reported. A possible reaction mechanism is considered and the structural assignments are supported by chemical and physical evidence.
