And the article was published in Organic Chemistry Frontiers in 2019. Name: 4-Iodobenzaldehyde The author mentioned the following in the article:
An efficient method for the synthesis of alkyl indium reagents by an indium(III) or lead(II) halide-catalyzed direct insertion of indium into alkyl iodides and their applications in palladium-catalyzed cross-coupling reactions with aryl halides is developed. NMR and ESI-MS analyses indicated that rather than the formation of the commonly recognized alkyl indium sesquihalide with the formulation of R3In2X3, the formed alkyl indium reagent in the present protocol should be a mixture of an alkyl indium dihalide (RInX2) and a dialkyl indium halide (R2InX) (both of them presumably exist as dimers). The results came from multiple reactions, including the reaction of 4-Iodobenzaldehyde(cas: 15164-44-0Name: 4-Iodobenzaldehyde)
4-Iodobenzaldehyde(cas: 15164-44-0) is used in synthesis of 4-[2-(trimethylsilyl)ethynyl]benzaldehyde, 5,15-dimesityl-10-(3-[2-(trimethylsilyl)ethynyi]phenyl}-20-(4-iodophenyl)porphyrin, and 5,15-dimesityl-10-[3,5-bis{2-[4-(N,N’-difluoroboryl-1,9-dimethyidipyrrin-5-yl)-phenyl]ethynyl}phenyl]-20-(4-iodophenyl)porphyrin.Name: 4-Iodobenzaldehyde
