t-Butylhydroperoxide reacts with trialkylstibines, R3M, to give the corresponding stibine oxides, R3MO, but with trialkylbismuthines to give products such as RO·OBut, ROH, and ROR. Both reactions are thought to involve the intermediate metallonium ion R3MOH, which undergoes nucleophilic attack on H when M = Sb, and on R when M = Bi.

Reduction by sodiumborohydride of the compounds R1R2C(OOBut) CH2·HgX, which are formed by t-butyl-peroxymercuration of terminal alkenes, leads to the formation of epoxides, R1R2[graphic omitted], in addition to the expected dialkylperoxides, R1R2C(OOBut)Me. The amount of epoxidation increases with increasing alkylation in the terminal alkene and with the temperature at which the reduction is carried
硼氢化钠还原化合物R 1 R 2 C(OOBu t)CH 2 ·HgX,这是由末端烯烃的叔丁基过氧汞固化形成的,导致形成环氧化物R 1 R 2 [略图],除预期的过氧化二烷基外,R 1 R 2 C(OOBu t)Me。环氧化的量随着末端烯烃中烷基化的增加以及进行还原的温度而增加。建议该结果与脱汞过程中碳汞键的均质裂解相一致。

A process for producing a polyorganosiloxanebased thermoplastic resin which comprises graft polymer-izing (3) at least one vinyl monomer using (4) an initiator which is an organic peroxide which, upon decomposition, produces an organic radical represented by the structural formula:
wherein R2, R3 and R4 represent independently hydrogen atoms or alkyl groups having 1 to 10 carbon atoms, in the presence of (2) a polyorganosiloxane.
