Against the rules: During the hundred years following Sabatier's groundbreaking work on catalytic hydrogenation, syn delivery of the H atoms to the π system of a substrate remained the governing stereochemical rule. An exception has now be found with the

2-Methyl-3,4-dihydro-1H-2-benzoselenopyranium salt (1) was reduced by some metallic reagents or magnesium metal via the single-electron transfer (SET) process to give 2--toluene (2).Magnesium metal was a good SET reducing agent.Some other selenonium or sulphonium salts (7), (14), (22), (27) and (32) were similarly reduced by magnesium.Particularly, sonication accelerated the reductions. ε-Eneselenonium salt (43) was treated with activated magnesium to give a cyclised pyrrolidine derivative (44).

Reaction of methylmagnesium iodide and phenylmagnesium bromide with thianaphthene, dibenzothiophenone, thianthrene, and 2,3-dihydrothiapyran in the presence of nickel dichloride have been shown to yield, regioselectively in most cases, ring-opened products in which the carbon-sulfur bonds have been replaced by carbon-carbon bonds.Stereospecific carbon-carbon bond formation has taken place in the reactions of thianaphthene and 2,3-dihydrothiapyran, the products having maintained the cis-olefin configuration of the starting sulfur compounds.Isomerization into the more stable compounds has been observed in some cases.
