Abstract
A parameter for the stabilization of the 3,4-bis(methylene)cyclobutene system has been identified. Appropriate functionalized derivatives, stable even in solution, have been conveniently prepared by tandem double [2,3]-sigmatropic rearrangement of conjugated dipropargylic sulfenates to diallenic disulfoxides and spontaneous cyclization of the latter. Stereochemical aspects are presented.
