Reactivity and Stability of a Ring-Expanded N-Heterocyclic Carbene Copper(I) Boryl Imidinate

چکیده
Frustrated Lewis pairs (FLPs) have evolved from a revolutionary concept to widely applied catalysts. We recently reported the ring-expanded N-heterocyclic carbene supported copper(I) boryliminomethanide, (6-Dipp)CuC(=NtBu)Bpin and noted it reacted with heterocumulenes in fashion reminiscent of FLPs. thus set out explore its reactivity range other substrates known react This was undertaken by series synthetic studies using NMR spectroscopy, mass spectrometry, IR single crystal X-ray crystallography. investigated for towards water, hydrogen, phenylacetylene. Its solution stability also explored. Upon heating, decomposed (6-Dipp)CuCN, which characterised SC-XRD pinBtBu. Although no reaction observed water form (6-Dipp)CuC(=N(H)tBu)B(OH)pin, structurally characterised. In contrast FLP-reminiscent heterolytic cleavage acted as Brønsted base phenyl acetylene generating (6-Dipp)CuCCPh, SC-XRD, IR, HC(=NtBu)Bpin

Reactions of the expanded ring N-heterocyclic carbene, 6-Dip (:C{N(Dip)CH2}2CH2, Dip = 2,6-diisopropylphenyl), with group 15 element trichlorides have yielded the monomeric complexes, [(6-Dip)ECl3] (E = P, As or Sb), two examples of which (E = P and Sb) have been crystallographically characterised. Reduction of [(6-Dip)PCl3] with KC8 yielded the unusual tetraphosphorus dicationic complex, [(6-D...
