| Research Abstract |
In oredr to develop the new thiocarbamoylizing and dithiophosphorylizing method, syntesis and reactions of carbamoylsulfenyl ( <R_2> NC(O)SX, X= halogen) and thiophosphorylsulfenyl halogenides [ (RO) <_2P> (S)SX, X= halogen ] have been investigated.
1. The reaction of zinc bis(thiocarbamate) and diphenyltin bis(thiocarbamate) with bromine and N-bromosuccinimide did not afoord the expected electrophilic carbamoylsulfenyl bromides, because of their extreme instability.
2. The reaction of O, O'-dialkyldithiophosphoric acid tin esters with bromine and N-bromosuccinimide was found to produce O, O'-thiophosphorylsulfenyl bromides which are an effective, electrophilic dithiophosphorylizing reagent under below 0 ゜C.
