The addition of some Iodine-based electrophillic reagents to the cyclic vinylsilanes (1) and (4,R=But,R1=H) and (4,R=H,R1-OMe) occurs with high regio-and stereo-specificity to give (2,X=OMe,N3, and NCS) and (5,R=But,R1=H,X=OMe and N3) and (5, R=H,R1-OMe,X-OMe). Similar additions to 2-trimethylsilylhept-1-ene (6) are less efficient and occur with lower regioselectivity. Some of the adducts (2) and (5)
将一些基于碘的亲电试剂添加到环状乙烯基硅烷(1)和(4,R = Bu t,R 1 = H)和(4,R = H,R 1 -OMe)中具有很高的区域和立体感-特异性给出(2,X = OMe,N 3和NCS)和(5,R = Bu t,R 1 = H,X = OMe和N 3)和(5,R = H,R 1 -OMe ,X-OMe)。对2-三甲基甲硅烷基庚-1-烯(6)的类似添加效率较低,且区域选择性较低。一些加合物(2)和(5)已被转化为官能化的有机硅烷。从而获得化合物(10,X = OMe,N 3和NCS)和(12)-(15)。
