Palladium complexes of the chiral diphosphanes 1 and 2 which possess a rigid backbone and a large bite angle catalyze the alkylation of allyl compounds with both high enantioselectivities and reaction rates, particularly with less sterically demanding substrates. 1: R=Me, X=S; 2: R=H, X=C(CH3 )2 .
具有刚性主链和大的咬合角的手性二膦1和2的钯络合物以高对映选择性和反应速率催化烯丙基化合物的烷基化反应,特别是对空间要求较低的底物。1:R = Me,X = S;2:R = H,X = C(CH 3)2。
