The Diels–Alder addition of dimethyl vinylphosphonates to cyclopentadienes: stereochemistry of the reaction using nuclear magnetic resonance spectroscopy
Abstract
The configurations of the adducts of dimethyl vinylphosphonate with cyclopentadiene, hexachlorocyclopentadiene, dimethoxytetrachlorocyclopentadiene, and pentachlorocyclopentadiene are established by n.m.r.
