Formylwolfram-Komplexe / Formyl Tungsten Complexes

Abstract

Abstract Bis(phosphite)-substituted formyl complexes (OC)2(ON)L2WCHO L = P(OMe)3 (4a), P(OEt)3 (4b), P(OiPr)3 (4c) were generated from the corresponding cationic (OC)3(ON)WL2 + system s using borohydride reagents. The decomposition of 4a-4c leads to hydride com pounds (OC)2(ON)L2WH or (OC)3(ON)LWH , L=P(OMe)3 (5a, 6a), L=P(OEt)3 (5b, 6b), L=P(OiPr)3 (5c, 6c).
