HETEROCUMULENE METATHESIS OF PB[N(SIME3)(2)](2) - HIGH-YIELD SYNTHESES OF THE HETEROLEPTIC DIMER (PH[N(SIME3)(2)(MU-OSIME3))(2) AND THE NOVEL LEAD(II) OXO CLUSTER PB-7(MU(3)-O)(MU(4)-O)(MU-OSIME3)(10)

Metathesis of Pb[N(SiMe3)(2)](2) (1) with 1 and 2 equiv of (BuNCO)-N-t
has been. used to prepare, in high yields, the novel lead(II) trimeth
ylsilanolato compounds {Pb[N(SiMe3)(2)(mu-OSiMe3)}(2) (2) and Pb-7(mu(
3)-O)(mu(4)-O)(mu-OSiMe3)(10) (4), respectively. Although [Pb(OSiMe3)(
2)](n) (3) could not be obtained through this process, these results s
erve to further elucidate the extents and limitations of heterocumulen
e metathesis as a synthetic tool.
