Synthesis and characterization of well-defined aluminum-containing heterobi metallic selenides

Abstract

A series of novel aluminum heterobimetallic selenicles were reported. The reaction of LAI(SeH)(2) (1) with LiN(SiMe(3))(2) resulted in the formation of [LAI(SeLi)(2)(THF)(2)] (2) (L = HC(CMeNAr)(2), Ar = 2,6-iPr(2)C(6)H(3))- Compound 2 reacted with Me(2)GeCl(2), Ph(2)GeCl(2), CP(2)TiCl(2), and CP(2)ZrCl(2), respectively, to produce LAI(mu-Se)(2)GeMe(2) (3), LAI(mu-Se)(2)GePh(2) (4), LAI(mu-Se)(2)TiCP(2) (5), and LAI(mu-Se)(2)ZrCp(2) (6) in moderate yields. Compounds 2-6 were characterized by elemental analysis, NMR, and electron impact-MS. The X-ray single-crystal structure of 3 is reported and confirms the spirocyclic arrangement of the aluminum atom within the six-membered AlN(2)C(3) and four-membered AlSe(2)Ge rings.
