As(SirBuMe,), (1) was prepared by the salt-elimination reaction between (Na/K), As and 'BuMe,SiCI. Mixing LiAs(SiMe,), with Ph,SiCl (1:l) yielded As(SiMe,),(SiPh,) (2) in a good crystalline yield. Reaction of 2 (1:I) with Et,Ga gave the expected Lewis acid-base adduct Et,Ga \* As(SiMe,),(SiPh,) (3).
The two hypersilylcuprates LiCu 2 Hyp 3 (2) and [Li 7 (O t Bu) 6 ][Cu 2 Hyp 3 ] (3) (Hyp = Si(SiMe 3 ) 3 ) were synthesized by reactions of unsolvated lithium hypersilanide, Li-Hyp with hypersilylcopper and CuO t Bu, respectively. Both contain the novel A-frame trihypersilyldicuprate anion [Cu 2- Hy
