An efficient one-pot approach to selenides: CuI-catalyzed reactions of magnesium selenolate with aryl or alkyl halides

An efficient one-pot route to symmetrical selenides in GC with yields from 13 to 94% has been developed by CuI catalyzing reactions of magnesium organoselenolates with aryl or alkyl halides under mild conditions. It is suggested that selenium could leave from PhSeMgBr to form other RSeMgBr with RMgBr based on experimental results. Although the leaving selenium causes low yield of unsymmetrical selenides and complex products, it offers a slowly releasing selenium source in preparation of nano metal selenides, and a potential leaving group in nucleophilic substitution. The role of excess magnesium is proposed.

Synthesis and NMR investigation of selenobutyl substituted silanes and oligosilanes

The reaction of BuSeLi, made from BuLi and elemental selenium, with chlorosilanes MexPhySiCl4-x-y led to selenobutyl substituted derivatives. In the cases of polychlorosilanes formation of the completely substituted products MexPhySi(SeBu)4-x-y are favoured. Higher yields of partially substituted products could be obtained by reaction of chlorosilanes with BuSeH/NEt3. Besides monosilanes the reactions of several methylchlorodi-, tri- and isotetrasilanes with BuSeLi and BuSeH/NEt3 were also investigated. In SiClMe(SiClMe2)2 the chlorine substituent at the middle silicon atom is substituted by BuSeH/NEt3 at first selectively. All products were characterized by 1H, 13C, 29Si and 77Se NMR and trends of chemical shifts and coupling constants (1JSiSi, 1JSiSe, 2JSiSe) with the substitution pattern were investigated.
