Synthesis and reactivity of zinc and aluminum alkyl derivatives stabilized by oxygen tripod ligands

Abstract

Zinc and aluminum alkyl derivatives L OEt ZnR (R=CH 3 , CH 2 CH 3 , CH(CH 3 ) 2 ) and L OEt Al(CH 3 ) 2 [Al(CH 3 ) 3 ] of the oxygen tripod ligand system L OEt ≡[CpCo{P(O)(OEt) 2 } 3 ] - (Cp=η 5 -C 5 H 5 ) have been synthesized by the reactions of the alkylis ZnR 2 and Al(CH 3 ) 3 with TlL OEt
