An environmentally benign protocol of chemoselective transfer hydrogenation of C=C and C=O bonds with alkanols under base-free conditions is developed by this study, wherein the cobalt- bidentate phosphine catalyst precursor is com. available and the active low-valent Co species could be generated in-situ. For the conjugation enones, the vinyl group is selectively reduced, whereas with nonconjugated alkenones the selectivity is changed to the carbonyl group. Besides, ortho-alkenyl-benzaldehydes/imines are well tolerated, and the reduction solely occurs at the C=O/C=N site with this protocol. In addition to this study using o-Bromobenzaldehyde, there are many other studies that have used o-Bromobenzaldehyde(cas: 6630-33-7Reference of o-Bromobenzaldehyde) was used in this study.
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.Reference of o-BromobenzaldehydeSynthetic applications of o-Bromobenzaldehyde include: synthesis of aza-fused polycyclic quinolines through copper-catalyzed cascade reaction, preparation of 1-substituted indazoles by CuI-catalyzed coupling with N-aryl hydrazides.
