Herein, we report the carbene-like activity of a nonisolable, highly ambiphilic cyclic (alkenyl)(amino)carbene (SMeCAenAC, 3), which is stabilized as [(SMeCAenAC)(H)N(SiMe3)2] (4). This protected form (4) stable in air and moisture. Compound 4 can be used carbene source through deamination upon heating to 130-140 °C. Moreover, density functional theory (DFT) calculations indicate that SMeCAenAC has smallest singlet-triplet gap (37.05 kcal/mol) narrow highest occupied molecule orbital...
Abstract The synthesis and reactivity of an air water stable Bicyclic (alkyl)(amino)carbene (BICAAC) stabilized phosphenium cation (1) is reported. Air are rare in the literature. Compound 1 obtained by reaction BICAAC with Ph 2 PCl THF followed anion exchange LiOTf. reduction oxidation yielded corresponding α‐radical phosphine species (2) oxide (3) respectively. All compounds well characterized single crystal X‐ray diffraction studies. Lewis acidity 3 determined conducting fluoride ion...
Herein, the synthesis and characterization of bicyclic (alkyl)(amino)carbene (BICAAC)-stabilized phosphinidenes (1-4) are reported. Compounds 1-3 were obtained by reacting trihalophosphine [PX3, X = Cl (1), Br (2), I (3)] with BICAAC in THF. A BICAAC-stabilized bis-phosphinidene (4) was from reduction compound 2. All four compounds characterized X-ray crystallography heteronuclear NMR spectroscopy. Theoretical calculations indicated predominant C(carbene)P double bond characteristic 1-4.
In this report, we synthesized heterobimetallic complexes supported by cyclic and bicyclic (alkyl)(amino)carbenes (CAAC EtBICAAC) [(Me2CAAC)CuFe(η5-C5H5)(CO)2](1) [(EtBICAAC)CuFe(η5-C5H5)(CO)2] (2), respectively, featuring an iron–copper bond. Complex 1 demonstrates catalytic activity for selective 1,4-hydroboration reactions of pyridine derivatives. Detailed computational studies provide additional insights into the electronic structure 2 elucidate pathway.
