Method for preparing perfluoroalkyl sulfonyl alkyne without metal or additive

The invention discloses a method for preparing perfluoroalkyl sulfonyl alkyne without metal or additive. The method comprises the steps that alkynyl aryl trivalent iodized salt and sodium perfluoroalkane sulfinate are mixed, reacting is conducted at minus 80 DEG C to minus 60 DEG C for 5 min to 24 h, separation and purification are conducted, and perfluoroalkyl sulfonyl alkyne is obtained. Sodium perfluoroalkane sulfinate can be prepared through sulfinatodehalogenation from perfluoroalky iodide very conveniently. The method is low in cost, diverse in type, rich in raw material source, mild in reaction condition, easy to implement and capable of being implemented in water and organic mixed solvent. The method for conducting perfluoroalkyl sulfonylation on alkynyl aryl trivalent iodized salt directly through sodium perfluoroalkane sulfinate without metal or any additive has good universality. According to the method, the raw materials are easy to obtain, the reaction condition is mild, the selectivity is good, the yield is high, the requirement on instruments and equipment is low, the technological operation is easy, and the method is expected to be used for synthesizing multiple trifluoromethoxy-containing pesticides, medicines, drug intermediates and novel materials on a large scale.

A novel sulfonamide non-classical carbenoid: A mechanistic study for the synthesis of enediynes

Alkynyl sulfonamides undergo sequential 1,4- then 1,2-addition/rearrangement with lithium acetylides to yield enediynes in the absence of any promoters or catalysts. Mechanistic investigations suggest that the reaction proceeds via 1,4-conjugate addition of the nucleophile to the unsaturated system to give a key alkenyl lithium species which is stabilised by an intramolecular coordination effect by a sulfonamide oxygen atom. This species can be considered a vinylidene carbenoid given the carbon atom bears both an anion (as a vinyllithium) and a leaving group (the sulfonamide). The intramolecular coordination effect serves to stabilise the vinyllithium but activates the sulfonamide motif towards nucleophilic attack by a second mole of acetylide. The resulting species can then undergo rearrangement to yield the enediyne framework in a single operation with concomitant loss of aminosulfinate.

Perfluoroalkanesulfonylation of Alkynyl(phenyl)iodonium Tosylates by the Weakly Nucleophilic Sodium Perfluoroalkanesulfinates

An additive- and transition metal-free perfluoroalkanesulfonylation of alkynyl(phenyl)iodonium tosylates with sodium perfluoroalkanesulfinates (RfnSO2Na) is described. The poorly nucleophilic RfnSO2Na reacted with alkynyl(phenyl)iodonium salts in dichloromethane at room temperature under a nitrogen atmosphere for 5–60 minutes to afford a variety of acetylenic triflones and alkynyl perfluoroalkyl sulfones in good to quantitative yields. The position of substituents on the phenyl rings of the arylethynyl moiety in the iodonium salts had a big influence on the reaction. The formation of five-membered cyclic vinyl sulfones suggested that the reaction proceeds via an alkylidene carbene intermediate. Furthermore, successful scaling-up of the reaction demonstrates the practicality of the new method. Advantages of the method include short reaction times, mild conditions, and the easy access to perfluoroalkanesulfonylation reagents (RfnSO2Na). (Figure presented.).

Stereo-and regiospecific syntheses of α- and β-substituted vinyl and dienyl triflones via the stille reaction

Acetylenic anions undergo efficient sulfonylation with trifluoromethanesulfonic anhydride to provide acetylenic triflones. These materials are stereospecifically converted to (Z)-β-iodovinyl triflones in one step via the addition of hydrogen iodide. Access to (Z)-α-iodovinyl trifloaes is also possible via a two-step process involving tributyltin hydride addition to the acetylenic triflones to generate (Z)-α-(tributylstannyl)vmyl triflones followed by an iododestannylation reaction. Both classes of iodovinyl triflones smoothly undergo palladium (O)-mediated Stille reactions with vinyl, aryl, heteroaryl, and acetylenic stannaries to stereospecifically provide trisubstituted vinyl and dienyl triflones.
