摘要
研究了铈汞齐、钐汞齐及CH_3I(或C_6H_5I)与羰基化合物的Barbier型一步法反应。同时研究了以微量I_2(或CH_2I_2)活化的金属铈、钐先与CH_3I(或C_6H_5I)反应生成相应的稀土甲基(或苯基)类格氏试剂,再就地与羰基化合物反应的二步法过程。按不同的稀土金属和实验条件得到加成产物或还原偶联产物。
The reactions of cerium and samarium amalgam with methyl and phenyl iodi-de in the coexistence of some carbonyl compounds (a one-step Barbier-type proce-dure)have been investigated The two-step Grignard-type procedure was carriedout using the reactions of Ce and Sm metals activated by a trace of CH_2I_2 or iodinewith CH_2I and PhI. The methyl and phenyl compounds thus prepared in situ reactwith some carbonyl compounds. All these reactions give adduct-product alcoholsand some reductive coupling product depending upon lanthanide metals, carbonylcompounds and reaction conditions.
