Article abstract of DOI:10.1039/c39920001725

Highly enantioselective hydrogenation of diketene with the catalytic system derived from (benzene)>Cl and triethylamine or with Ru2Cl4<(S)- or (R)-binap>2(NEt3) in tetrahydrofuran gives optically active 4-methyloxetan-2-one in up to 97percent selectivity and 92percent enantiomeric excess (e.e.).
