Process for the monoalkylation of C-H acid methylene groups

The ratio of the alkali(ne earth) carbonate to the methylene group-containing substrate is above 0.6 : 1 in the monoalkylation of C-H acid methylene groups by reaction of the substrate in a polar aprotic solvent with a dihalogen compound having its halogens separated by a chain of at least3C and with reaction being in presence of the alkali(ne earth) carbonates and a phase transfer catalyst and being accompanied by continuous removal of the water formed. An Independent claim is also included for production of omega-haloalkyl-nitriles or -carboxylic acids by reacting a malonic acid diester or cyanoacetic ester with an alpha,omega-dihaloalkane as above and then saponifying and decarboxylating the product.
