对于SH 2过程R·+ PhSeSePh → PhSeR + PhSe·,k=ca。5 × 107 mol-1 s-1;对于1-金刚烷基自由基,这种SH 2置换提供了1-金刚烷基苯基硒化物的途径,在氧化和热解所得硒氧化物时,得到金刚烷-1-醇;相反,来自双环[3.3.1]壬-1-基苯基硒化物的硒氧化物通过双环[3.3.1]壬-1-烯分解。
For the SH2 process R·+ PhSeSePh → PhSeR + PhSe·, k=ca. 5 × 107 mol–1 s–1 at 80 °C in benzene when R is primary alkyl; with 1-adamantyl radicals this SH2 displacement affords a route to 1-adamantyl phenyl selenide which, on oxidation and pyrolysis of the resultant selenoxide, gives adamantan-1-ol; in contrast the selenoxide from bicyclo[3.3.1]nonan-1-yl phenyl selenide decomposes via bicyclo[3.3.1]non-l-ene.
