A considerable extension of the synthetic potential of lithium arsenides is likely through the alanates [LiAl(AsHR)4] (RH, triorganosilyl), which can be synthesized from LiAlH4 and H2AsR. For example, the Zintl compound [Li(tmeda)]3 As71 was obtained by thermal decomposition in the presence of tmeda, and the first As4Si4 cubane was prepared by mild arsanylation of RSiCl3 (R2,4,6-iPr3C6H2). The novel complex 2 with an adamantane framework was formed from RAsH2 (RMe2C(iPr)SiMe2) and LiAlH4. tmedaMe2NCH2CH2NMe2, dmeMeOCH2CH2OMe.
