achieve radical boryl substitutions of a variety of alkyl radical precursors. Dehalogenative, deaminative, decharcogenative, and decarboxylative borylations proceeded in the presence of a radical initiator to give the corresponding organic boron compounds. Radical clock experiments and computational studies have provided insights into the mechanism of the homolytic substitution (SH2) of the borylstannanes
(o -Phenylenediamino)borylstannanes是新合成的,可实现多种烷基自由基前体的自由基硼基取代。在自由基引发剂的存在下进行脱卤,脱氨基,脱碳和脱羧基的硼化反应,得到相应的有机硼化合物。自由基时钟实验和计算研究提供了对硼烷基锡烷被烷基中间体中间体均质取代(S H 2)的机理的见解。DFT计算表明,苯二胺基结构降低了LUMO能级,包括硼原子上的空位p-轨道,从而增强了对S H 2中烷基的反应性。此外,C(sp 3使用x吨酮的三重态完成THF的H-硼化反应。
