Chemistry of Heterocyclic Compounds | 1982

Synthesis and study of the light-stabilizing activity of some dithiocarbamates that include a heteroaromatic ring

Ya. L. Gol'dfarb; E. G. Ostapenko; V. B. Ivanov; A. F. Efremkin; V. P. Litvinov

A number of new dithiocarbamates of transition metals that contain thiophene, furan, benzo[b]thiophene, and benzo[b]selenophene rings were synthesized. The compounds obtained were investigated as light stabilizers for polymers. It is shown that the effectiveness of the light-stabilizing effect of the dithiocarbamate depends on the structure of the heterocyclic fragment included in its composition.
