Benzyl chloromethyl ether reacts with carbonylcompounds in the presence of SmI2 to afford alcohols (I), which are subsequently subjected to hydrogenolysis to yield diols (II).

Enantiocontrol in CH insertionreactions of 3° alkyl diazoacetates, which is highly dependent on the catalyst ligand, is greatly enhanced with the use of dirhodium(II) tetrakis[methyl 1-acetylimidazolidin-2-one-4(S)-carboxylate], Rh2(4S-MACIM)4.
