Direct application of benzyl alcohols (or their magnesium salts) as electrophiles in various reactions with Grignard reagents has been developed via transition metal-catalyzed sp(3) C-O bond activation. Ni complex was found to be an efficient catalyst for the first direct cross coupling of benzyl alcohols with aryl/alkyl Grignard reagents, while Fe, Co, or Ni catalysts could promote the unprecedented
已经通过过渡金属催化的 sp(3) CO 键活化开发了苯甲醇(或其镁盐)在与格氏试剂的各种反应中作为亲电试剂的直接应用。发现 Ni 配合物是苯甲醇与芳基/烷基格氏试剂首次直接交叉偶联的有效催化剂,而 Fe、Co 或 Ni 催化剂可以促进苯甲醇在( n) 己基MgCl。这些方法提供了将苯甲醇转化为各种功能的直接途径。
