Abstract
Organoditolyldithiophosphates corresponded to [(o-, m- and p-CH 3 C 6 H 4 O) 2 PS 2 C(O)R] (R = CH 3 -, CH 2 CH 3 - and C 6 H 5 -) and (o-, m- and p-CH 3 C 6 H 4 O) 2 PS 2 C 6 H 4 CHO have been synthesized by the displacement reactions of acetyl chloride (CH 3 COCl), propionyl chloride (CH 3 CH 2 COCl), benzoyl chloride (C 6 H 5 COCl) and ortho-, meta- and para-chlorobenzaldehyde (o-, m- and p-ClC 6 H 4 CHO) with sodium O,O′-ditolylphosphorodithioates, (o-, m- and p-CH 3 C 6 H 4 O) 2 PS 2 Na, in equimolar ratio in refluxing toluene. These colored viscous compounds were characterized by elemental analyses, molecular weight determination, IR and NMR ( 1 H, 13 C and 31 P) spectroscopic studies, which revealed monodentate mode of bonding of the dithio moiety with the carbon atom of the organic moiety, leading to an arrangement containing P─S─C linkage.
