Cross‐Si‐ing the Jordan: Cross‐coupling reactions of 2‐(2‐hydroxyprop‐2‐yl)phenyl‐substituted alkylsilanes with a variety of aryl halides proceed in the presence of palladium and copper catalysts. The use of K3PO4 base allows for highly chemoselective alkyl coupling with both primary and secondary alkyl groups (Alk).
乔丹的交叉反应:2-(2-羟基丙-2-基)苯基取代的烷基硅烷与各种芳基卤化物的交叉偶联反应在钯和铜催化剂的存在下进行。K 3 PO 4碱的使用允许与伯烷基和仲烷基(Alk)都高度化学选择性的烷基偶联。
Réactions non classiques au cours de l'alkylation de dérivés d'éléments de la colonne IVB par des réactifs de Grignard
The reduction of derivatives of the type RnSiσ4-n (σ = Cl, OCH3) by some organomagnesium compounds RMgX at high temperature (⩾80°) leads to the hydrosilanes RR'SiH2 and RR'2SiH in various ratios according to the considered reagents. The results described in this publication constitute a first approach in the knowledge of the mechanism of these reductions. A deeper study of the mechanism is the subject
