Phenols were vinylated at the ortho-position with ethyne in the presence of SnCl(4)-Bu(3)N reagent. The reaction was applicable to phenols possessing either electron-donating or electron-withdrawing groups. 2,6-Divinylphenols were synthesized under modified conditions. A reaction mechanism involving carbostannylation of alkynyltin and phenoxytin was discussed.
在SnCl(4)-Bu(3)N试剂存在的情况下,在乙炔的邻位乙烯基化乙烯基苯酚。该反应适用于具有给电子或吸电子基团的酚。在改性条件下合成了2,6-二乙烯基苯酚。讨论了炔基锡和苯氧基锡的羰基化反应的反应机理。
