Reaction of 1,2-borylphosphinoethene with thiocyanates. Molecular and crystal structure of 2,2,3-tributyl-4,5,5-triphenyl-6-methylthio-1,5,2-azaphosphoniaboratacyclohexa-3,6-diene
摘要:
The reaction of 1,2-borylphosphinoethenes with alkylthiocyanates leads to formation of substances having the structure of 6-alkylthio-1,5,2-azaphosphoniaboratacyclohexa-3,6-dienes in the crystal state. The structure of the compounds has been proven by x-ray diffraction analysis of 2,2,3-tributyl-4,4,5-triphenyl-5-methylthio-1,5,2-azaphosphoniaboratacyclohexa-3,6-diene. The heterocyclic moiety of the molecule is planar within 0.010(2) angstrom. The methylthio group lies practically in the plane of the heterocycle.
