Excellent regiocontrol is achieved in the rhodium-catalysed hydroformylation of some alkenyl phosphites, and good stereocontrol is obtained in the hydroformylation of some cyclohexenyl phosphites.The stereochemical results have implications for the mechanism of these rhodium-catalysed reactions.

Catalytic cyclometallation of styrene, m-methylstyrene, p-tert-butylstyrene, and 1-hexene with di n-alkylmagnesium compounds (n-R2Mg, where R=C3H7, C4H9, C6H13) in the presence of Cp2Zr2Cl2 has been given high yields of 2,4-disubstituted magnesiocyclopentanes.The probable mode of formation of magnesiocyclopentanes, involving zirconocyclopentanes formed from Cp2ZrCl2, n-R2Mg, and the appropiate olefins as reactive intermediates in the cyclometallation, is discussed. Keywords: catalytic synthesis, substituted styrenes, alkenes, magnesium alkyls.

Phosphite esters can be used to give excellent regiocontrol in rhodium catalysed hydroformylation reactions of alkenes and in addition excellent stereocontrol in the reactions of some cyclohexenyl phosphites.
