Et3SiOCH2NMe2, readily made in high yield by the hydrosilylation reaction between Et3SiH and DMF, is an excellent (N,N-dimethylamino)methyl transfer agent to a representative range of aliphatic alcohol, thiol and Ph2PH (E-H) materials. The reactions are almost instantaneous at room temperature in inert solvents and require no activating agents to produce E-CH2NMe2 products in high yield and illustrate the
三乙基甲硅烷氧基甲基胺Et3SiOCH2NMe2易于通过Et3SiH和DMF之间的氢化硅烷化反应以高收率制备,对于脂族醇,硫醇和Ph2PH(EH)材料的代表性范围而言,它是一种出色的(N,N-二甲基氨基)甲基转移剂。反应在室温下在惰性溶剂中几乎是瞬时的,不需要活化剂即可高产率生产E-CH2NMe2产品,并说明标题化合物是有机试剂家族的绝佳添加。对于芳族醇,芳族官能团的亲电子取代以高收率发生。报道了诸如胆甾醇基-CH 2 NMe 2衍生物,2-4-4- [双(N,N-二甲基氨基)甲基] -1-萘酚和衍生自Ph 2 PCH 2 NMe 2的氧化膦的新材料的晶体结构。
