Abstract
The title compounds 3a, b result from the condensation of the ylidyldi chlorophosphines Ph(3)PCR-PCl2 1a, b (R = Me, 3-Tol) with phenyl bis(t rimethylsilyl)phosphine 2. Analysis of the P-31-NMR spectra and the X- ray structure investigation of 3 a demonstrate a folding of the four-m embered ring and an all-trans orientation of the substituents.
