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.
对于S H 2过程,R·+ PhSeSePh→PhSeR + PhSe·,k = ca。当R为伯烷基时,在苯中80°C,5×10 7 mol –1 s –1;具有1-金刚烷基的该S H 2置换提供了通往1-金刚烷基苯基硒化物的途径,其在所得硒氧化物的氧化和热解后,产生了金刚烷-1-醇。与此相反,从双环的氧化硒[3.3.1]壬烷-1-基苯基硒化物分解经由二环[3.3.1]壬-1-烯。

Reaction of 5-hexenyltributyltin with pseudohalogen electrophiles leads to either double bond addition products or cyclization products. When electrophiles containing non-nucleophilic counterions are used, predominately cyclization products are formed.
