Reactions of aryl isocyanide with bis(guanidinate) Zr(IV) hydrocarbyl complexes are presented. With 1 equiv of Ar′NC the ultimate products are the terminal Zr imido complexes [{(R′NR″)C(NR)2} 2ZrN(2,6-Me2C6H3)] (3, R=R′ = iPr, R″ = H; 5, R.= iPr, R′ = R″ = Me), which are derived via a unique transformation from intermediate η2-iminoacyl species. With 2 equiv ofAr′NC, [{(Me 2N)C(NiPr)2}2Zr(η2- Ar′N-CMe)2](6) was isolated. Mild thermolysis of 6 generates an enediamido complex via intramolecular coupling of the iminoacyl groups.
