An efficient copper(I)‐catalyzed coupling of triaryl and trialkylindium reagents with aryl iodides and bromides is reported. The reaction proceeds at low catalyst loadings (2 mol %) and generally only requires 0.33 equivalents of the triorganoindium reagent with respect to the aryl halide as all three organic nucleophilic moieties of the reagent are transferred to the products through consecutive transmetalations

mild, copper-catalyzed coupling of organoindium reagents with nitrogen-containingaromaticheterocycles and chloroformates is described. This reaction proceeds with a range of organoindium reagents, yielding predominately or exclusively the 1,4-addition products with pyridine. In addition, a range of other nitrogen-containingheterocycles can be employed in this reaction (e.g. benzoxazole, benzothiazole

of 4-functionalized quinazolines in good to excellent yields. Higher yields were obtained by the one-pot reaction of quinazolinone, p-methylbenzenesulfonyl chloride, Pd2(dba)3-/(2-furyl)3P, and organoindium reagent. These methods using organoindium compounds as coupling partners provided an efficient route to 4-(hetero)aryl/alkylquinazolines, especially 4-substituted quinazolines bearing a halogen scaffold

Convenient synthetic routes to trisisopropylindan, bisisopropylindiumbromide, and -iodide as well as isopropylindiumdiiodide are reported. The reactivity of isopropylindiumdiiodide towards chalcogenols (C2H5EH; E = S,Se) has been investigated. The spectra and some physical and chemical properties of the new compounds are described.

The reaction of In(CH2Ph)3 and InMes3 with BF·OEt2 forms the corresponding monofluorides (PhCH2)2InF(1) and Mes2InF (2), while [iPr2In][BF4] (3) is precipitating, when BF3·OEt2 is given to a solution of In(iPr)3 in ether. 3 can be recrystallized from an Et2OTHF-mixture as colorless needles of [iPr2In(THF)2][BF4] (4). An X-ray structure determination of 4 shows [iPr2In(THF)2]+-ions, bridged by [BF4]−-ions
