C07C 29/38 by reaction with aldehydes or ketones
Introduced: January 1980
Full Title
Full titles differ between systems:
Preparation of compounds having hydroxy or O-metal groups bound to a carbon atom not belonging to a six-membered aromatic ring > increasing the number of carbon atoms by reactions with formation of hydroxy groups, which may occur intermediates being derivatives of hydroxy groups, e.g. O-metal > by reaction with aldehydes or ketones
