undergoes a SNAr reaction with sulfinyloxy-trifluoroborates to produce the corresponding 2,4-dinitrophenylsulfone. The developed method allows the transformation of potassium allyltrifluoroborates into allyl sulfones.
钾allyltrifluoroborates进行了bora-烯与二氧化硫在不存在路易斯酸催化剂的,得到亚磺酰-三氟硼酸,其随后经历烷基化与亲电子,以产生在砜高达91%产率反应。苄基卤化物和卤代乙酸衍生物可用作烷基化试剂,而Sanger试剂与亚磺酰氧基三氟硼酸酯进行S N Ar反应,生成相应的2,4-二硝基苯砜。所开发的方法允许将烯丙基三氟硼酸钾转化为烯丙基砜。

p-Toluenesulfonyl radical can be generated by the manganese(III) acetate oxidation of sodium p-toluenesulfinate. The corresponding alkyl radicals could be produced effectively by the p-toluenesulfonyl radical induced radical reaction of allylsulfonyl substituted N-aryl amides. These alkyl radicals undergo 5-exo-trig, 6-endo-trig, or 6-exo-trig cyclization onto the aromatic ring effectively. The product

for the synthesis of 2-chloroprop-2-en-1-yl sulfones in 47–94% yield. The molecular and crystal structures of 2-chloroprop-2-en-1-yl phenyl sulfone and 2-chloroprop-2-en-1-yl methyl sulfone were determined by X-ray analysis. π-Stacking interaction between the benzene ring and double bond was revealed in the crystal structure of 2-chloroprop-2-en-1-yl phenyl sulfone. Chloropropenyl sulfones were found
