Synthesis and structure of trimethylsilyl and diethylboron derivatives of p-toluene-N-nitrosulfonamide

1. The silylation of the Ag salt of N-nitro-p-toluenesulfonamide with trimethylchlorosilane, or of the free N-nitro-p-toluenesulfonamide with N,N′-diphenyl-N-trimethylurea, gave the O-trimethylsilyl derivative of N-nitro-p-toluenesulfonamide. 2. The reaction of the Ag salt of N-nitro-p-toluenesulfonamide with diethylboron chloride gave the O-diethylboron derivative of N-nitro-p-toluenesulfonamide. Treatment of the derivative with pyridine gave the bis(pyridyldiethylboronium) salt of N-nitro-p-toluenesulfonamide.
