Reactions of phenylaluminium compounds with E(SiMe3 )3 (E = P or As): X-ray crystal structures of Ph3 Al · E(SiMe3 )3 (E = P or As) and Ph2 (CI)Al · P(SiMe3 )3
The independent reactions of Ph3Al with E(SiMe3)3 (E = P or As) in 1:1 mole ratios afforded the adducts Ph3Al · E(SiMe3)3 [E = P (I) and As (II), respectively]. The attempted dehalosilylation reactions between Ph2AlCl and E(SiMe3)3 (E = P or As) in 1:1 mole ratios yielded only the adducts Ph2(Cl)Al · E(SiMe3)3 [E = P (III) and As (IV)]. The adduct Ph(Cl)2Al · P(SiMe3)3 (V) was isolated from the reaction of equimolar amounts of PhAlCl2 and P(SiMe)3. Compounds I-V were characterized by NMR spectroscopy and partial elemental analysis. In addition, the solid-state structures of I-III were determined by single-crystal X-ray analysis. Compound I crystallizes in the monoclinic space group P21/n (C52h), while II crystallizes in the triclinic space group P1̄(C1i), each with two discrete molecules per asymmetric unit. Crystals of compound III belong to the orthorhombic space group P212121,(D42). Compounds I-III are the first structurally-characterized compounds to contain phenyl-substituted Al centres bonded to heavier pnicogen atoms. Copyright © 1996 Elsevier Science Ltd.
