    • Dibenzyltrithiocarbonate was synthesized by a two step process according to the ref 39. In the first step sodium trithiocarbonate was prepared in a l L reactor equipped with a stirrer and a thermometer and charged with 146.3 g of hydrated sodium sulfide (1.125 mol, 350 mL of water, 6 g of methyltributylammonium chloride in 6.7 g water, and 88.4 g carbon disulfide (1.15 mol, The reaction mixture was stirred for 60 min, and the solution turned bright red as sodium trithiocarbonate formed. In the second step, 255 g of benzyl chloride (2 mol) were added slowly over a period of 15 min. The reaction temperature rose to 50 °C. The stirring was maintained for 3 hours and then the mixture was heated to 70 °C for 30 additional minutes. To drive the reaction to completion a second catalyst charge containing 3.8 g of methyltributylammonium chloride in solution in 5. l g water was added. The reactor was left overnight under stirring without heating. The organic phase was then isolated, an
