摘要

The (π-allyl) palladium complex bearing an sp2-hybridized phosphorus ligand (DPCB-OMe: 1, 2-bis (4-methoxyphenyl)-3, 4-bis [(2, 4, 6-tri-tert-butylphenyl) phosphinidene] cyclobutene) efficiently catalyzes direct conversion of allylic alcohols in the absence of activating agents of alcohols such as Lewis acids. N-Allylation of aniline proceeds at room temperature to afford monoallylated anilines in 90-97% yields. C-Allylation of active methylene ...
