发明人：JERPHAGNON THOMAS; PASTORI JOEL
权利人:FIRMENICH & CIE
摘要:The present invention relates to the field of organic synthesis. More specifically, it concerns a process for the selective reduction of a C 3 -C 70 substrate containing one or more carbonyl or carboxylic functional groups into the corresponding 5 alcohol diol, or polyalcohol in the presence of a silane and at least one catalyst or pre-catalyst in the form of a zinc complex. The Zinc complex of formula (I) or (II) is also part of the invention.
