1,170,514. Esters and amides containing chloromethyl and acrylic or methacrylic residues. FARBENFABRIKEN BAYER A.G. 31 Jan., 1967 [25 March, 1966], No. 4636/67. Heading C2C. [Also in Division C3] (a) Compounds of the formula CH 2 = CR-CO-NH-CH 2 -NHCO-CH 2 Cl (where R is H or methyl) are prepared by reacting equimolar amounts of N-methylolchloroacetamide and (meth)acrylamide in glacial acetic acid in the presence of cone. HCl and phenothiazine. (b) The compound of formula CH 2 = C(CH 3 ) -COO-CH 2 -CH(CH 3 )-OOC-CH 2 Cl is prepared by reacting equimolar amounts of #- hydroxypropyl methacrylate and chloroacetic acid in toluene in the presence of p-toluene sulphonic acid and 2,6-di-t-butylphenol-4-methylol methyl ether, while removing water of reaction azeotropically. (c) The compounds of formula CH 2 = C(CH 3 )- CO-A-CO-NH-CO-CH 2 Cl (where A is -NH- or -O-CH 2 -CH(CH 3 )-O-) are prepared by reacting equimolar amounts of chloromethylacylisocyanate and methacrylamide or #-hydroxypropyl methacrylate respectively in dry toluene.
