Direct nucleophilic displacement of iodine to give (Me3Si)3 CSiMe2 Y, where Y = F, NCO, NCS, CN or N3, takes place when (Me3Si)3 CSiMe2I is treated with solutions of CsF, KOCN, KSCN, KCN, or NaN3 in MeOH or CH3 CN. The order of effectiveness of the nucleophiles appears to be N3 > F > CN > NCS > NCO in MeOH and NCS > NCO > CN, F in CH3 CN.
当用CsF溶液处理(Me 3 Si)3 CSiMe 2 I时,发生碘的直接亲核置换,得到(Me 3 Si)3 CSiMe 2 Y,其中Y = F,NCO,NCS,CN或N 3。在MeOH或CH 3 CN中的KOCN,KSCN,KCN或NaN 3。亲核试剂的有效性顺序似乎是:MeOH中的N 3 > F> CN> NCS> NCO和CH 3 CN中的NCS> NCO> CN,F 。
