regioselective synthesis of highly functionalized pyranopyrazoles was achieved in excellent yield from phenyl pyrazolone, substituted aromatic aldehyde with nitroketene-n,s-acetal in the presence of indium trichloride as a versatile catalyst under reflux condition in ethanol-water mixture. all reactions preceeded within a short period of time with excellent purity. all of the synthesized compou...

The title compound, hexa-mu-chloro-1:2kappa(4)Cl;2:3kappa(4)Cl;3:4kappa(4) Cl-hexachlor o-1kappa(2)Cl,2kappaCl,3kappaCl, 4kappa(2)Cl-hexakis(diethylamine)-1kappa(2)N,2kappa N,3kappaN, 4kappa(2)N-tetraindium(III), [(InCl(3))(4)(Et(2)NH)(6)] or [In(4)Cl(12)(C(4)H(11)N)(6)], lies about an inversion centre and consists of four octahedrally coordinated In centres linked by bridging Cl atoms to form ...

Allyl and 2-methylallyl indium compounds were prepared by salt metathesis starting from indium trichloride and a Grignard reagent. They are highly fluxional in solution and reveal coordination numbers of the indium atoms of four and five in the solid state.

Indium trichloride, benzyl alcohol, and triethylamine (without an added 'directing' multidentate ligand) generate a catalyst in situ for the room temperature polymerization of D,L-lactide affording highly heterotactic polylactide of controlled molecular weight and narrow molecular weight distribution.

Treatment of indium trichloride with three equivalents of the cyclopentadienyliron carbonyl anions, [Fe(C O )2(?7-C5H4R)] (R = H, Me) affords the tri-iron indium com plexes [In{Fe(C O )2(//-C5H 4R )},] (R = H. Me) as dark red crystalline materials. Both compounds were characterized by spectroscopic and analytical methods. Infrared spectroscopy indicates that both com plexes are undissociated in...

Indium trichloride reacts with 2 moles of monothiodibenzoylmethane (LH ) in the presence of sodium acetate to yield InC l2L(LH ). According to an X-ray structure analysis the molecule possesses a hexacoordinated indium atom with two chlorine atoms in cis position and two sulfur atoms in trans position. The symmetry of the molecule is C2 imposed by a crystallographic twofold axis. The unique hyd...

A versatile and high-yielding indium trichloride mediated cyclization reaction of silylated homoallylic alcohols, thiols, or amines with aldehydes or epoxides is described as a rapid route to a range of unsaturated heterocycles. The excellent diastereoselectivity observed offers a method of wide scope and generality.

A series of (±)- and (R,R)-tridentate diamino, ortho/para disubstituted phenolate proligands H(NNO(R)) with various phenolate substituents was synthesized and used to prepare indium dichloride complexes (NNO(R))InCl2via salt metathesis of the deprotonated ligands with indium trichloride. These complexes are dinuclear in the solid state, in contrast to previously reported complexes with t-butyl ...
