An Alkynylaminomethylaluminum Species with a Six-Membered Chair Conformation Al2C2N2 Framework: A New Path to Geminal N/Al Frustrated Lewis Pairs
摘要:
The hydroalumination of the fused pentahydride aminocarbaaluminum species [(C6H3(iPr(2)-2,6)N(mu-AlH2)CH2)(2)(mu-AlH)NMe3] (1) with phenylacetylene resulted in the unexpected dimer [C6H3(iPr(2)-2,6)(*N)HCH2Al(CCPh)(2)](2) (2) with chiral centers at the nitrogen atoms. Compound 2 was characterized by X-ray structural analysis and contains geminal frustrated Lewis pairs.
