Dialkylamino-3,4-dimethyl-5-phenyl-1,3,2-oxazaphospholane sulfides (where the alkyl is an isopropyl, ethyl or methyl group) was obtained by sulfurization of the respective phospholanes. The structures of these compounds were determined by X-ray crystal structure analysis. Five-membered rings exist in the envelope conformation in the crystalline state. The planar part of the 1,3,2-oxazaphospholane rings undergoes twisting with the enlargement of a substituent. The environment of the Patom has the geometry of a distorted tetrahedron.
