Preparation of new Thiazyltrifluoride Derivatives by Si-N Bond Cleavage Reactions

In this study, we investigate the preparation of new thiazyltrifluoride derivatives through silicon-nitrogen bond cleavage reactions. The objective was to synthesize NSF2-N(CH3)2 and NSF2-N(C2H5)2 derivatives using thiazyltrifluoride as a precursor. Methodologically, we conducted reactions involving (CH3)3Si-N=SF2=N-Si(CH3)3 as a starting material in conjunction with SF4 and P2O3F4 to yield NSF2-N=SF2 and O=PF2-N=SF2=N-PF2=O, alongside minor quantities of other products. Additionally, we explored the reactions of this starting compound with dimethylamine and piperidine, resulting in new imido compounds. The findings reveal that using lithiumhexamethyldisilazide in petroleum ether can yield bis(trimethylsilylimido)sulfur difluoride and tris(trimethylsilylimido)sulfur, indicating the versatility of thiazyltrifluoride in generating complex nitrogen-silicon compounds. The study contributes to a better understanding of the reactivity of thiazyl derivatives and expands the potential applications for these compounds in the field of inorganic and organic chemistry.
