Benzidine was found to be a novel transient directing group to enable Pd-catalyzed direct selenylation of inert C(sp2)-H bonds of benzaldehydes. Diverse diarylselenides were readily constructed in high efficiency and satisfactory yields with good functional group tolerance. The practical usage of the method was further demonstrated by enlarged reaction to gram scale and application in the facile access to two selenoxanthenes and one fluorescent probe. The experimental part of the paper was very detailed, including the reaction process of o-Bromobenzaldehyde(cas: 6630-33-7SDS of cas: 6630-33-7)
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.SDS of cas: 6630-33-7It is also used in L-threonine aldolase-catalyzed enantio and diastereoselective aldol reactions. Further, it reacts with trichloromethane to prepare 1-(2-bromo-phenyl)-2,2,2-trichloro-ethanol.
