Synthesis of the rhenium allyl chloride complex Cp*Re(η3-C3H5)(CO) Cl and reactions to give hydrido, phenyl and alkyl derivatives

Abstract

Abstract The rhenium η 3 -allyl chloro complex Cp * Re(η 3 -C 3 H 5 )(CO)Cl ( 5 ) has been synthesized from the photolysis of Cp * Re(CO) 3 and allyl chloride, or from the reaction of the cationic complex [Cp * Re(η 3 -C 3 H 5 )(CO) 2 ] + with PhIO and Me 4 NCl. Complex 5 is readily converted to the η 3 -allyl hydrido complex Cp * Re(η 3 -C 3 H 5 )(CO)H by reaction with LiBEt 3 H, and to the phenyl or alkyl derivatives Cp * Re(η 3 -C 3 H 5 )(CO)Ph or Cp * Re(η 3 -C 3 H 5 )(CO)R by treatment with LiPh or Grignard reagents.
