A facile synthesis of 2-oxo-cyclopentenylphosphonates by carbonylation of zirconacyclopentenylphosphonate with oxalyl chloride
摘要:
Addition of oxalyl chloride to zirconacycles prepared from 1-alkynylphosphonates 1 zirconocene dichloride, and two equivalents of EtMgBr smoothly produced novel 2-oxo-cyclopentenylphosphonates 6 in 58-81% isolated yields in the presence of a copper catalyst.
