Abstract

Synthesis of the first oxaphosphirane chromium(0) and molybdenum(0) complexes of the type [{(R1PCH(R2)-O}M(CO)5] (R1 = C5Me5) (8a–e, 15a–e) and (R1 = CH(SiMe3)2) (9a–e, 16a–e) via reaction of dichloro(organo)- (1, 2, 10, 11) and chloro(organo)phosphane complexes (3,4,12) with lithium bases and aldehydes 7a–e is reported. Furthermore, bicyclic 1,3-oxaphospholane complexes 17 and 18 have been obtained via O-protonation of oxaphosphirane complexes 8a and 15a with HCl. All complexes were characterized by NMR, IR spectroscopic, mass spectrometric investigations and, in addition, single-crystal X-ray structures of complexes 8a–e, 9a,c, 15a,b,e, 16a–c, 17, 18 are presented and discussed.
