In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Lee, Shao-Chi; Guo, Lin; Rueping, Magnus. Electric Literature of C27H39ClN2. The article was titled 《Nickel-catalyzed exo-selective hydroacylation/Suzuki cross-coupling reaction》. The information in the text is summarized as follows:
The first nickel-catalyzed intramol. hydroacylation/Suzuki cross coupling cascade of phenylboronic acid neopentyl glycol esters I (R = Ph, anthracen-9-yl, thiophen-2-yl, etc.) with a broad range of o-allylbenzaldehydes 2-CH2=CHCH2-4-R3-5-R2-6-R1C6HCHO (R1 = H, R2 = H, OMe; R1R2 = CH=CHCH=CH; R3 = H, OMe, Me, F) has been developed. This strategy shows high regioselectivity and step economy in the construction of two C-C bonds via aldehyde C-H bond activation, affording valuable indanones II with high efficiency. In the experiment, the researchers used 1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0Electric Literature of C27H39ClN2)
1,3-Bis(2,6-diisopropylphenyl)-4,5-dihydro-1H-imidazol-3-ium chloride(cas: 258278-25-0) has been employed in an efficient, one-pot synthesis of N-heterocyclic carbene-allylpalladium complexes.Electric Literature of C27H39ClN2In addition, it can efficiently catalyze the Suzuki-Miyaura coupling of aryl chlorides with aryl boronic acids.
