A variety of aryltin compounds can be employed for Michael-type hydroarylation reactions to α,β-unsaturated ketones and aldehydes in the presence of a catalytic amount of palladium(II) salt in acetic acid under air. Each reaction is much accelerated in the presence of a soluble metal chloride such as LiCl, MgCl2, and CaCl2. It is found that slightly fewer than four aryl groups of tetraaryltins can
多种芳基锡化合物可用于在乙酸中在催化量的钯 (II) 盐存在下,在空气中进行迈克尔型加氢芳基化反应,生成 α,β-不饱和酮和醛。在可溶性金属氯化物如 LiCl、MgCl2 和 CaCl2 的存在下,每个反应都会大大加速。发现在该芳基化反应中,四芳基锡的芳基略少于四个可以转移到产物中。
