719-80-2, General procedure: 2-Chloromethylbenzothiazole (1) (0.183 g, 0.001 mol) andpotassium iodide (KI) (0.166 g, 0.001 mol) were taken intoa round bottomed flask containing 20 mL of THF. Thereaction mixture was stirred for 3 h at 40C. After completionof the reaction as checked by TLC, cooled the reactionmass to RT and then filtered to remove the salt (KCl),resulted in iodo compound, 2-(iodomethyl) benzo[d]thiazole(2). The filtrate was transferred into a flask and sodiumazide (NaN3) (0.065 g, 0.001 mol) was added. The reactionmixture was stirred at 25-30C for 3 h to form an intermediate,2-azidomethylbenzothiazole (3). The reaction mixturewas filtered to remove the salt, NaI, and filtrate was takenfor the next step.Triphenylphosphine (4a) (0.262 g, 0.001mol) was added to 3under N2 atmosphere. The reaction mixture was stirred at 65-70C for 4 h and the progress of the reaction was monitored byTLC using ethylacetate: n-hexane (2:3) as an eluent. After completionof the reaction, the solvent was removed from the reactionmixture in a rotaevaporator to get the crude product and itwas purified by column chromatography using ethylacetate:nhexane(1:4) to obtain pure product, N-(1,3-Benzothiazol-2-ylmethyl)-N-(1,1,1-triphenyl-lambda5-phosphanylidene) amine (5a).The same procedure was adopted for the synthesis of remainingtitle compounds and the physical data of these compounds aresummarized in Table 1.
