Molecular structure of cis-syn-cis isomer 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

It has been shown by x-ray structure analysis that the interaction of 2-phenyl-5-methyl-1,2,3-diazophosphole with diazopropane forms, along with the cis-anti-cis isomer, the cissyn-cis isomer of 2,2,6,9-tetramethy1-4,11-dipheny1-4,5,10,11-tetraaza-1,3-diphosphatricyclo-[6.3.0.03,7]undeca-5,9-diene. © 1985 Plenum Publishing Corporation.
