Both C-Cl bonds of CH(2)Cl(2) are readily activated by CoCl(2) and metallic Zn allowing quantitative methylation of phosphines; unprecedented zwitterionic Co(ii) and Zn(ii) intermediates have been characterized which display alpha-metallated phosphoniums.
二氯甲烷的两个碳氯键都能被二氯化钴和金属锌轻易活化,从而实现膦的定量甲基化;已对前所未有的两性离子钴(II)和锌(II)中间体进行了表征,这些中间体显示出α-金属化鏻盐。
