T. Yokomatsu et al., Diels-Alder cycloaddition of novel buta-1,3-diene derivatives possessing a(diethoxyphosphinoyl)difluoromethyl unit, CHEM COMMUN, (18), 2001, pp. 1878-1879
A series of new buta-1,3-diene derivatives possessing a (diethoxyphosphinoy
l)difluoromethylene unit at the terminal carbon was prepared to examine the
reactivity for Diels-Alder cycloaddition with various representative dieno
philes.
