Diverse C–P cross-couplings of arylthianthrenium salts with diarylphosphines producing various triarylphosphines via highly selective C–S bond cleavage are reported. In the absence of catalyst, the reaction of arylthianthrenium salts with diarylphosphines undergoes phosphinative ring opening exclusively via the cleavage of an endocyclic C–S bond of a thianthrene skeleton. The use of a palladacycle
据报道,芳基噻吨鎓盐与二芳基膦通过不同的C–P交叉偶联,可通过高选择性的C–S键裂解产生各种三芳基膦。在没有催化剂的情况下,芳基噻吨鎓盐与二芳基膦的反应仅通过裂解噻吩骨架的内环C–S键进行膦化开环。在其他条件相同的情况下使用Palladacycle催化剂,则可以通过裂解环外C-S键以更高的速度进行磷酸化反应。
