Selenium was reduced with borohydride exchange resin (BER) in methanol at room temperature to give probably a selenide exchange resin. It reacted with alkyl halide or tosylate to give dialkyl selenides selectively in a quantitative or high yield without forming toxic hydrogen selenide and/or foul-smelling selenol.

Fluoride ions smoothly destannylate organotin chalcogenides to liberate nucleophilic chalcogenide ions; hence the first nucleophilic oxide (O2-) and selenide (Se2-) transfer agents are reported where the tin atom serves as "group 16 (VIB) transfer agent".In the presence of crown ethers or ammonium salts, this process results in a new way to generate "naked" nucleophiles.Ethers and selenides are formed in good to excellent yield.In addition, a useful C-C bond-forming reaction has been developed by using alkyltins with aldehydes and acid chlorides in the presence of fluroide ion.Aspects concerning reactivity and mechanism are presented.Finally, the generality of the fluorodestannylation procedure and the differences with parallel silicon chemistry are detailed.

Pyrolyses of a series of selenides and diselenides were studied. Selenides and diselenides bound with an active methylene group like benzyl gave a variety of substituted bibenzyls and related ethane derivatives in high yields. Other diselenides were easily caused to cleave to give various aromatic and aliphatic olefins in good yields together with elemental selenium. Lepidopterene, paracyclophane, and benzocyclobutene were prepared by thermal cleavage of their corresponding phenylselenomethyl-substituted compounds as an application of the pyrolysis concerned.
