X-ray structural investigation of the adduct of 1,3-di(tert-butyl)-2,4-di(tert-butylamido)diazadiphosphetidine with carbon disulfide and 2,5-diphenyl-3-cyclohexyl-4-oxo-4-cyclohexylamido-1,3,4-oxazaphospholidine

摘要: An x-ray structural investigation of the products reactions 1,3-di(tert-butyl)-2,4-di(tert-butylamido)diazadiphosphetidine and 1,3-dicyclohexyl-2,4-di(cyclohexylamido)diazadiphosphetidine with carbon disulfide benzaldehyde, respectively, has been carried out (λMo, 2006 1484 reflections, R=0.038 0.083). It shown that in former reaction four-membered P2N2 ring is maintained, a new exocyclic bond appears between one its P atoms atom formation zwitterionic adduct formula C15H38N4P2·CS2. In latter case opened, five-membered heterocycle closed 2,5-diphenyl-3-cyclohexyl-4-oxo-4-cyclohexylamido-1,3,4-oxazaphospholidine C26H35O2N2P. The geometric parameters both molecules investigated have analyzed detail.
