    Abstract: Prodn. of chlorothioformate esters of formula R-S-CO-Cl (I) is effected by reacting a thiol of formula R-SH (II) with CoCl2 in the presence of a catalytic amt. of a cyclic tert. amine (III), where R = an organic gp. (III) is a mono- or dialkylated 5- or 6-membered aromatic or nonaromatic heterocyclic cpd. contg. 1 or 2 tert. N atoms, where the alkyl gps. contain a total of 5-20 C atoms.

    Abstract: Catalyst produced by reacting methanolamine with ethylene oxide used in the prodn. of methoxypropionitrile from acrylonitrile and methanol according to the Parent patent was found equally effective with respect to reactions of acrylonitrile with mono- or polyhydric alcohols contg. >=2C atoms. The resulting title cpds can be used as inters. in the prodn. of acid amides, amines or diamines, isocyanates, etc. The catalyst is relatively inexpensive.
