Synthesis of ammonium ions and nitrosylation reactions using nitrosyl chloride and alkyl nitrites
Abstract
Nitrosyl chloride (NOCl) reacts with RuCl3·xH2O in the presence of PPh3 in different alcohols leading to the formation of ammonium ions and [Ru(NO)Cl3(PPh3)2] under mild experimental conditions, through reductive deoxygenation. Some parameters affecting the reactivity of the redox system have been qualitatively defined. Similar reactions in tetrahydrofuran do not yield [NH4]+ ions. Alkyl nitrites (RONO, R = Me or Et) have also been successfully employed as nitrosylating agents for the syntheses of nitrosyl complexes of RuII, RuIII, RhI, and IrI.
