catalytically active Ni(0) species generation stage, Ni(PCy3)2X2 (X=Cl, Br) could also be efficient catalysts for the cross-coupling reactions a variety of aryl/activated alkenyl tosylates with arylboronic acids. The mild reaction condition, the easy availability of the catalysts and excellent coupling yields make these catalyst systems potentially useful in organic synthesis.
室温镍(II)配合物[(4-MeOC 6 H 4)Ni(PCy 3)2 OTs和Ni(PCy 3)2 X 2(X = Cl,Br)]催化的芳基/烯基交叉偶联反应描述了具有芳基硼酸的磺酸盐。镍(II)络合物(4-MeOC 6 H 4)Ni(PCy 3)2 OTs被证明是芳基磺酸盐与芳基硼酸的Suzuki-Miyaura交叉偶联反应的一般催化剂。通过限制初始催化活性的Ni(0)物种产生阶段的水量,Ni(PCy 3)2 X 2(X = Cl,Br)也可能是多种芳基/活化的烯基甲苯磺酸酯与芳基硼酸的交叉偶联反应的有效催化剂。温和的反应条件,容易获得的催化剂以及出色的偶联收率使得这些催化剂体系潜在地可用于有机合成。
