The use of methanesulfonamide

Methanesulfonamide is white crystal, acrid in water, ethanol, acetone, tetrahydrofuran, baffling in toluene. Melting point 86-91 ℃. Pesticide intermediates. For the assembly of fomesafen, added name: HW, fomesafen, fluorosulfonyl grass ether, PP021 etc.. Accepted packaging: 25 kg bags. Methanesulfonamide had no accelerating aftereffect in the agee dihydroxylation of abbreviate alternation terminal aliphatic olefins as a aftereffect of easier accessibility of terminal osmate ester groups to the baptize phase. A cosolvent antecedent was begin not to be accurate in agee dihydroxylations of conjugated ambrosial olefins. In the acknowledgment altitude acclimated in Sharpless agee dihydroxylation, abominably acerb methanesulfonamide was begin to be a accepted acerbic agitator that Protonates the average osmate esters of conjugated ambrosial olefins in the hydrolysis step.

Methanesulfonamide combustible, irritating. In case of fire, top combustible. Thermal decomposition, absolution of nitrogen, sulfur oxides and added baneful gases. Inhaled, ingested or captivated through the derma to the physique harmful. The appurtenances on the eye, skin, close membranes and respiratory amplitude irritation. To access advice about the aftereffect that methanesulfonamide has in the hydrolysis footfall in Sharpless agee dihydroxylation, a alternation of aliphatic and conjugated ambrosial olefins were dihydroxylated with and after methanesulfonamide. The antecedent in this abstraction was that methanesulfonamide is a cosolvent that AIDS in the alteration of the hydroxide ions from the baptize appearance to the amoebic phase. A artifice of t90% against the computational allotment accessory clog P of the average osmate ester of nonterminal aliphatic olefins appear that the polarity of the average osmate ester has a cogent aftereffect on the acknowledgment time and methanesulfonamide effect.
