Syntheses and molecular structure of organo-group 13 metal carbene complexes

Trimethylaluminium or trimethylgallium reacts with 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene 1 to afford the first organo-group 13 metal carbenes 2 (M = Al 2a, Ga 2b), which are characterized by elemental analyses, IR, 1H and 13C NMR spectroscopy, and single-crystal X-ray diffraction.

Synthesis and Molecular Structure of Germanium and Tin Tetraphenylbutadienyl Based Heterocyclic Halides

The reaction of 1,4-dilithiotetraphenylbutadiene with germanium(IV) chloride and tin(IV) chloride affords heterocycles Ph4C4GeCl2, I and Ph4C4SnCl2, II. Compounds I and II, which feature a planar tetraphenylbutadiene backbone, were characterized by elemental analyses, 1H and 13C NMR spectroscopy and single crystal X-ray diffraction. The coordination environments for germanium and tin are distorted tetrahedra with bond angles spanning 35.35° for I and 24.86° for II. The Ge[sbnd]Cl and bond distances are 2.134 A and 2.143 A in I, while the Sn[sbnd]Cl and bond distances are 2.313 A and 2.312 A in II.

Formation of a diphosphine: synthesis and molecular structure of bis(tetraphenylbutadienyl)diphosphine, (Ph4C4)P–P(C4Ph4)

Reaction of 1,4-dilithiotetraphenylbutadiene with phosphorus(III) bromide affords bis(tetraphenylbutadienyl)diphosphine, (Ph4C4)P–P(C4Ph4), with a phosphorus–phosphorus bond length of 2.2051(11) A.

2,6-Bis(2,4,6-triisopropylphenyl)phenyl as an extraordinarily bulky ligand in organometallic chemistry. Synthesis and molecular structure of [(Mes*2C6H3)MCl2]2 (M = Ga, In; Mes* = C6H2Pri3-2,4,6)

Gallium chloride or indium chloride interacts with 2,6-bis(2,4,6-triisopropylphenyl)phenyllithium, (Mes*2C6- H3)Li (Mes* = C6H2Pri3-2,4,6), affording [(Mes*2C6H3)MCl2]2 (M = Ga 1, In 2), interesting group 13 organometallic crystalline dimers, characterized by elemental analyses, 1H and 13C NMR spectroscopy, and single-crystal X-ray diffraction.

Synthesis and Molecular Structure of (Mes2C6H3)B(Br)N(H)[i-Pr2C6H3)] and an ab initio Examination of CH3BBr2 and CH3B(Br)NH2

Reaction of (2,6-dimesitylphenyl)boron dibromide, (Mes2C6H3)BBr2. I, with [2,6-di-i-propylphenyl)amino[lithium, [(i-Pr2C6,H3)N(H)Li, affords 2,6-dimesitylphenyl](2,6-di-i-propylphenyl)amino]boron bromide, (Mes2C6H3)B(Br)N(H)[(i-Pr2C6H3)] II. II has been characterized by elemental analyses, 1H and 13C NMR, and single crystal X-ray diffraction. ab initio examination of model molecules CH3BBr2, III, and CH3B(Br)NH2, IV, supports a measure of π-bonding in the B‒Br and B‒N bonds in III and IV.

Synthesis, molecular structure, and reactivity of an Li2Br4 octahedrally stabilized organoaluminium bromide dimer

The synthesis, molecular structure, and reactivity of an unusual Li2Br4 octahedrally stabilized organoaluminium bromide dimer, [(Mes2C6H3)AlBr3Li]2, is described.

Synthesis and molecular structure of an unusual –Ga–Ga–Ga– linked organometallic

Reaction of [(2,4,6-Pri3C6H2)2C 6H3]GaCl2 with P(SiMe3)3 affords the unusual organometallic compound [(2,4,6-Pri3C6H2)2C 6H3]Ga{H2PGa(H)PH2}G a[C6H3(C6H2- Pri3-2,4,6)2] 1 characterized by multinuclear NMR, complete (C, H, Ga and P) elemental analyses, IR spectroscopy and single crystal X-ray diffraction; 1 is significant as it contains a rare Ga–Ga–Ga [2.5145(13) and 2.7778(14) A] linkage even as its formation is facilitated by the unusual stripping of the sterically demanding m-terphenyl ligand from the central gallium atom.
