A one-pot reaction of alcohols with trimethylsilyl cyanide and methanesulfonic acid with subsequent neutralization by triethylamine and dehydration by tosyl chloride and pyridine gave the corresponding isocyanides in moderate-to-high yields. This method was used to synthesize tertiary and benzylic isocyanides from the corresponding alcohols. isocyanides -alcohols- Ritter reactions

This method can be used for the efficient and practical synthesis of various N-substituted formamides without the use of unmanageable cyano compounds. A facile and versatile method for preparing N-substituted amidesfrom alcohols and amides using a Brønsted acid and an alkali metal halide has been developed. Treatment of tertiary alcohols and amides in the presence of an alkali metal halide or methanesulfonic
a single step from tertiaryalcohols. A direct method for preparing bis(alkylamino)maleonitriles from alcohols was developed. Treatment of tertiaryalcohols with trimethylsilyl cyanide (TMSCN) and trimethylsilyl triflate (TMSOTf) in the presence of bismuth(III) triflate [Bi(OTf)3] afforded the corresponding bis(alkylamino)maleonitriles in moderate-to-high yields. Tertiaryalcohols with various functional
