A highly chemoselective route to aryl methyl sulfones via an unexpected C–S bond formation between sulfonylhydrazides and dimethyl phosphite catalyzed by NaI under mild conditions has been established. This transformation provides an alternative an

Synthesis (Stuttg)
A new reductive coupling reaction between N-alkylisatins, dimethyl phosphite, and nitrostyrenes has been developed. The reaction relies on Pudovik addition, subsequent phosphonate–phosphate rearrangement, and Michael-type addition of a transient ca

The addition of phosphorous acid on the C=O group of substituted benzaldehydes in the presence of hydrochloric acid in water affords a mixture of the corresponding α - chlorophosphonic acid and α-hydroxyphosphonic acid. The selectivity towards the

A new synthesis of 1-(N-sulfonylimino)alkanephosphonates via the one pot three-component reaction of sulfonyl azides, terminal alkynes, and dimethyl or diphenyl phosphite catalyzed by copper(I) iod...

The coupling of dimethyl phosphite and iodobenzene occurs in the presence of catalytic amounts of homoligand carbonyl complexes of chromium subgroup metals to form dimethyl phenylphosphonate in yields of 50–73% depending on the metal.

An alternative approach is reported for the synthesis of methyl ester protected bisphosphonate building blocks, such as methylene bisphosphonate, vinylidenebisphosphonate and aryl substituted prochiral vinylidenebisphosphonates, that cannot be obtain

The addition of dimethyl phosphite to N,N'-terephthalylidene-alkyl- (or aryl-) amines resulted in new tetramethyl 1,4-phenylene-bis-(N-alkylaminomethyl)-phosphonates in moderate yields. The stereochemical behaviour of these reactions was studied by N
