Silicones with this functionality are the ligands in Karstedt's catalyst, which catalyzes a reaction between Si-H groups and compounds of this type in a hydrosilylation reaction. Molecules of this type can be formed from benzothiazol-2-yl sulfones and aldehydes in a one-step base catalyzed reaction. That one-step reaction gives high stereoselectivity and avoids the need for a second step using sodium amalgam which produces a freely rotating planar radical. In the food industry, molecules containing this group are reacted with a (*) nickel catalyst with hydrogen gas under heat and pressure in order to create margarine and shortening from oils. For 10 points name this
