The reaction of vinyl bromides bearing distal olefin or acetylene functionalities with tetracarbonylnickel in the presence of alcohols and triethylamine results in the formation of exo-methylene cyclic esters in a regioselective process. High influence of the bulkiness of the alcohol is found.
在醇和三乙胺的存在下,带有远端烯烃或乙炔官能团的溴化乙烯与四羰基镍的反应在区域选择性过程中形成外亚甲基环状酯。发现醇的松散度的高度影响。
