Synthesis of the new water soluble vinyl ruthenium complex [RuCp(=C=CPh)(PPh3)(mPTA2](CF3SO3) (mPTA = N-methyl-1,3,5-triaza-7-phosphaadamantane): chemical reactivity and catalytic properties for redox isomerization of allylic alcohols

Abstract

The Ruthenium(II) phenylvinylidene complex [RuCp(=C=CHPh)(mPTA)(PPh 3 )](CF 3 SO 3 ) 2 (2) has been synthesized and characterized by NMR, IR and elemental analysis and its structure by single crystal X-ray diffraction (mPTA = N-methyl-1,3,5-triaza-7-phosphaadamantane). The chemical reactivity of this complex against water, acid medium, O 2 , CO, isopropylamine, cyclohexylamine, 2-aminopyridine, ethanethiol and ethanol was studied. As a result, new amino and thio-carbenes were obtained and characterized. Additionally, complex 2 was evaluated as catalyst for the isomerisation of linear allylic alcohols with different tail lengths.
