The contents of a flask charged with n-heptanal (2.5 mmol), sodium trichloroacetate (2.7 mmol) and a solvent (10 g) were stirred for 16 hours. At the end of this period, when the reaction mixture contained sodium 1,1,1-trichloro-2-octyl carbonate (compound 24), ##STR35## water (50 ml) was added and the mixture was extracted with two portions (each of 25 ml) of n-pentane. Six experiments were thus carried out, each with another solvent. Table I shows which solvents and temperatures were used and presents the conversion of the n-heptanal and the selectivity to the title alcohol. These conversions and selectivities were already obtained after one hour stirring, stirring being continued overnight.
