The stannaborate complexes (Ph3P)(H11B11Sn)Pt(tBuNC)[C(Ph)NHtBu]} (2) and {
(ddpe)(H11B11Sn)Pt[C(Ph)NHtBu]} (4) were obtained by insertion of tBuNC int
o the Pt-Ph bond of [Bu3MeN][trans-(Ph3P)(2)Pt(Ph)(SnB11H11)] and [Bu3MeN][
(dppe)Pt(Ph)(SnB11H11)] at room temperature. The insertion products were ch
aracterized by elemental analysis, NMR spectroscopy, and X-ray crystal stru
cture analysis.
