Herein, the synthesis of new low-valent Group 14 phosphinidenide complexes [({SIDipp}P)2M] exhibiting P-M pπ-pπ interactions (SIDipp = 1,3-bis(2,6-diisopropylphenyl)-imidazolidin-2-ylidene, M = Ge, Sn, Pb), is presented. These compounds were studied by structural, spectroscopic, and quantum-chem. methods. Furthermore, the monosubstituted compounds [(SIDippP)MX]2 (M = Sn, X=Cl; M = Pb, X = Br) are presented, which show dimeric structures instead of multiple bonding interaction. The results came from multiple reactions, including the reaction of 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Computed Properties of C27H39ClN2)
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0) may be used as a precursor to the free carbene 1,3-bis(2,6-diisopropylphenyl)-2-imidazolidinylidene, and also used as an in situ formed catalyst in a variety of reactions, e.g. amination, Heck coupling reaction, the ring-opening metathesis polymerization (ROMP), hydrogenation.Computed Properties of C27H39ClN2In addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
