摘要

Abstract: Single-crystal X-ray analysis of the sulfur-containing spirocyclic phosphorane (CH~ C~ H &)(CI~ H~ O~) PP~(111) revealed a geometry only slightly displaced from a rectangular pyramid. The X-ray analyses of the related thio spirocyclics,(C6H40S) 2PPh (IV) and (C6H&) 2PPh (V), showed geometries closer to the idealized trigonal pyramid. Ill crystallizes in the monoclinic space group P2l/n, with a= 9.816 (2) A, b= 14.047 (2) A, c= ...
