Synthesis of monoorganotin(IV) chloride complexes of cis-1,2-bis(diphenylphosphino)ethylene: Solution and solid state structures
چکیده انگلیسی

Organotin(IV) complexes of the type [RSnCl3(cis-Ph2PCHCHPPh2)] [R = Me (1), nBu (2), Ph (3)] were prepared by the reaction of RSnCl3 with the rigid bisphosphine ligand, cis-1,2-bis(diphenylphosphino)ethylene in dichloromethane. The complexes have been characterized both in solution and the solid state. Low temperature 31P and 119Sn NMR studies indicate two different phosphorus environments. The crystal structures indicate a weak but chelating mode of coordination of the two phosphorus atoms to tin, leading to a distorted octahedral geometry. In solution the complexes 1–3 undergo a redistribution reaction to form [SnCl4(cis-Ph2PCHCHPPh2)] (4) as one of the products. In order to confirm the redistribution, complex 4 has been prepared separately and characterized both structurally and spectrally.

The reaction of RSnCl3 with cis-Ph2PCHCHPPh2 yields chelate complexes [RSnCl3(cis-Ph2PCHCHPPh2)] [R = Me (1), nBu (2), Ph (3)]. The complexes have been characterized both in solution and solid state. In solution, the complexes undergo redistribution to form [SnCl4(cis-Ph2PCHCHPPh2)] (4).Figure optionsDownload as PowerPoint slide
