SYNTHESIS AND REACTIONS OF HIGHLY STERICALLY HINDEREID ORGANOSILICON COMPOUNDS OF THE TYPE (Me3Si)3CSi(C6H4-OMe-p)MeX AND (Me3Si)3CSi(C6H4-Me-p)MeX
摘要:
Direct nucleophilic displacement of TsiSi(C6H4-OMe-p)MeI and TsiSi(C6H4-Me-p)MeI with nucleophiles take place. These compounds also react with electrophiles such as AgOAc and AgNO3 to give rearrangment products, for example (Me3Si)(2)C(SiMe(2)OAC)SiMe2 (C6H4-Y-p) (Y = Me, OMe). The hydrides and bromides of these compounds were also synthesised.

Direct nucleophilic displacement of halide X (X=Cl or I) takes place when the compounds (Me3Si)3CSiRR′X with R=Me, R′=(C6H4Me-p), (C6H4OMe-p), CH2CH R=Bu, R′=Cl, or R=Ph, R′=Ph are treated with solutions of KOCN, KSCN, KCN, or NaN3 in CH3CN or MeOH, and H2O in DMSO, or CH3CN.
