defined for the desulphurisation of ethylene dithioacetals with nickelboride. Normally a mixture of saturated and unsaturated products is formed. Nickelboride is inferior to Raney nickel for the desulphurisation of thiophens. Hemithioacetals are rapidly cleaved by nickelboride, allowing regeneration of the ketone. Triterpene2-enes are obtained in excellent yield from 3-ketones by desulphurisation
