Abstract: Abstract The complex Pt(IPr)(SnBut3)(H), 1 [IPr=N-heterocylic carbene ligand N,N’-bis-(2,6-(diisopropyl)phenyl)imidazol-2-ylidene] reacts with trimethylsilylacetylene to yield the C-H activation product Pt(IPr)(SnBut3)(κ1-C≡CSiMe3)(H)2, 2. Complex 2 isomerizes to form the unique complex Pt(IPr)[η2-E-(SnBut3)(H)C=C(SiMe3)(H)], 3. This demonstrates that in addition… read more here.
