1-Isopropyl-4,6-dimethyl-6-phospha(V)bicyclo[3.1.1]hept-3-ene 6-oxide: a distorted phosphetan synthesized from α-pinene and the methylphosphonous dichloride–aluminium chloride complex; X-ray crystal and molecular structure
Abstract
Reaction of α-pinene with MePCl2–AlCl3 gives the title compound (4), a bridged bicyclic phosphetan, whose structure has been unequivocally assigned on the basis of chemical, spectral, and X-ray analysis.
