A single method (2% Pd(2)(dba)(3)/8% PCyp(3)/NMI in THF/NMP at 80 degrees C; Cyp = cyclopentyl) achieves the cross-coupling of a range of beta-hydrogen-containing primary alkyl iodides, bromides, chlorides, and tosylates with an array of alkyl-, alkenyl-, and arylzinc halides. The process is compatible with a variety of functional groups, including esters, amides, imides, nitriles, and heterocycles
单一方法(2% Pd(2)(dba)(3)/8% PCyp(3)/NMI in THF/NMP 在 80 摄氏度;Cyp = 环戊基)实现了一系列 β-氢的交叉偶联- 包含伯烷基碘化物、溴化物、氯化物和甲苯磺酸盐以及一系列烷基-、烯基-和芳基卤化锌。该工艺与多种官能团兼容,包括酯、酰胺、酰亚胺、腈和杂环。
