Synthesis and molecular structure of 2,2,6,9-tetramethyl-4, 11-diphenyl-4,5,10,11-tetraaza-1,3-diphosphatricyclo[6.3.0.03,7] undeca-5,9-diene

Abstract

1. The reaction of 2-phenyl-5-methyl-1,2,3-diazaphosphole with diazapropane yields the first example of the cycloaddition of a phosphorus diylide at the dicoordinated phosphorus P=C bond. 2. X-ray structural analysis unequivocally indicated the structure of the product of this reaction and gave its molecular geometry. © 1983 Plenum Publishing Corporation.
