Zinc dithiocarbamates are used in the rubber industry as rapid vulcanization accelerators. Especially zinc diethyldithiocarbamate (ZDC), zinc butyldithiocarbamate (ZBC) and zinc dimethyldithiocarbamate (ZDMC) must be classed as contact allergens (Cronin 1980 , Fuchs 1995 , Lamintausta and Kalimo 1985, Rademaker and Forsyth 1988 , Zugerman 1981 ).

Dithiocarbamates are used as pesticides and rubber additives. Dithiocarbamates are the reduced forms of thiuram disulfides and both of these groups of substances induce allergic contact dermatitis. The allergic cross-reactivity pattern between dithiocarbamates and thiurams is unclear. The aim of this study was to investigate why these cross-reactions occur sometimes but not always. HPLC

The Mechanism of Zinc(II)-Dithiocarbamate-Accelerated
This is achieved by incorporating sulfur atoms in the zinc-dithiocarbamate ring and inducing their insertion into an allylic C−H bond via an ene-like reaction. This ene reaction yields a rubber-bound polythiothiol and is only slightly endothermic, even though an activation energy of ∼90 kJ mol-1 is required.
