Abstract

Treatment of benzyl halides with silver salts (AgClO₄, AgBF₄, or AgOTf) and trimethylsilyl cyanide (TMSCN) in CH₂Cl₂ followed by cleavage of the carbon-silicon bond with aqueous NaHCO₃ or TBAF directly afforded the corresponding isocyanides.

Key words

benzyl isocyanides - benzyl halides - silver salts - trimethylsilyl cyanide - perchlorate
