The reaction of RhCl(PPh3)3 with Et2Zn easily generated a rhodium-hydride complex (Rh-H) that added to α,β-unsaturated esters to form rhodium enolate complexes by formal 1,4-reduction. These rhodium enolates gave the corre

A Reformatsky-type reaction has been developed using iron catalysis in acetonitrile or DMF. Reduction of iron(II) bromide by manganese metal in acetonitrile provides a low-valent iron catalyst, which is the active species; under these conditions, α-chloro
The stereoselective synthesis of oxetanes; exploration of a new, Mitsunobu-style procedure for the cyclisation of 1,3-diols

A solution of 2-methyl-3-[1-(phenylsulfanyl)cyclohexyl]propane-1,3-diol 1 in toluene treated with triphenyl-phosphine, Ziram 2 and DEAD, gave 3-methyl-2-[1-(phenylsulfanyl)cyclohexyl]oxetane 3 in 85% yield. A mechanistic study has been undertaken, optimal conditions have been found and the range of substrates for which the reaction is useful has been explored. We include the results of an X-ray study which shows that compound 33 (the oxidation product of diol 1) is a sulfone rather than a sulfoxide as previously reported.
