Pentacoordinate 1,2-azaphosphetidines bearing the Martin ligand were synthesized by the intramolecular dehydration of the corresponding β-amino phosphine oxides with Mitsunobu reagent (Ph3P-EtO2CN=NCO2Et). The X-ray crystallographic analysis of 1,2,4,4,-tetraphenyl derivative shows that it has a distorted trigonal bipyramidal structure with oxygen and nitrogen atoms at apical positions. Their thermolyses gave the corresponding olefins along with a cyclic iminophosphorane, which was readily hydrolyzed to give the cyclic phosphinate and aniline.

The oxetanes containing highly coordinate B, Si, Ge, Sn, P, S, and Se and an azaphosphetidine were successfully synthesized. All compounds except B and Sn compounds have the Martin ligand. The X-ray crystallographic analysis indicated that they have a dis
