The activation of yellow arsenic is possible with the silylene [ePhC(NtBu)(2)SiN(SiMe3)(2)] (1) and the disilene [(Me3Si)(2)N(eta(1)-Me5C5)Si=Si(eta(1)-Me5C5)N(SiMe3)(2)] (3). The reaction of As-4 with 1 leads to the unprecedented As-10 cage compound [(LSiN(SiMe3)(2))(3)As-10] (2; L - PhC(NtBu)(2)) with an As-7 nortricyclane core stabilized by arsasilene moieties containing silicon(II) ...
