The article conveys some information:
A highly efficient sulfonylation of para-quinone methides with sulfonyl hydrazines in water has been developed on the basis of the mode involving a tetra-Bu ammonium bromide (TBAB)-promoted sulfa-1,6-conjugated addition pathway. This reaction provides a green and sustainable method to synthesize various unsym. diarylmethyl sulfones, showing good functional group tolerance, scalability, and regioselectivity. Further transformation of the resulting diarylmethyl sulfones provides an efficient route to some functionalized mols. The experimental process involved the reaction of o-Bromobenzaldehyde(cas: 6630-33-7Application of 6630-33-7)
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.Application of 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.
