Abstract
PURPOSE: To obtain the titled compound useful as an intermediate for an organic fine chemical, safely and in high selectivity, by the reaction of an arylacetate and formaldehyde with carbon monoxide in the presence of a tertiary amine, a small amount of water and a catalyst.
CONSTITUTION: An arylacetate expressed by the formula ArCH2COOR (Ar is an aromatic group; R is 1W6C alkyl) and formaldehyde in a molar amount of 1.2W6.0 times that of the arylacetate are reacted with carbon monoxide under a presence of 10W200kg/cm2, preferably in the range of 50W100kg/cm2, in the presence of a tertiary amine, preferably N-methylmorpholine, a small amount of water in a molar amount of 0.5W10 times that of the arylacetate and a rhodium compound, e.g. rhodium trichloride or dichlorotetracarbonyl-dirhodium, as a catalyst, at 150W 220°C, to give the titled compound.
