Metal-Containing Heterocycles: Preparation, Properties, Reactions, LXIII. - Phosphamolybdacyclopropanes with Carbene and Phosphinidene Building Blocks

The phosphidomolybdate Li2PPh2> (1) = (η5-C5H5)Mo(CO)2> reacts with the geminal dihalides RCHCl2 (2a-c) a), Me (b), Ph (c)> and the organophosphorus chlorides RPCl2 (4b-d) to give the three-membered phosphamolybdacyclopropanes (3a-c) and (5b-d), respectively.The activation parameters ΔG for the rotation of the P-C unit are independent of the substituent R, based on temperature-dependent 1H-NMR spectra of 3a-c.According to an X-ray structural analysis 5c crystallizes in the triclinic space group P with Z = 4.Compared to a single bond the P-P distance (211 pm) in 5c is shorter.The complexes (OC)5MTHF are added to the Lewis basic phosphinidene phosphorus in 5c with loss of THF giving (6c-8c) . - Key Words: Phosphamolybdacyclopropanes / Isolobal building blocks
