  decarboxylative functionalization of acrylic acids has been developed. The reaction uses inexpensive organic dye 9,10-dicyanoanthracene as a photocatalyst and uses the ubiquitous dioxygen as both an oxygen source and an oxidant. Through this mild and environmentally friendly method, a series of important α-thiocyanate ketones can be generated from easily available acrylic acids and ammonium thiocyanate. In

  Synthesis of α-heterosubstituted ketones was achieved through sulfur mediated difunctionalization of internal alkynes in one pot. The reaction design involves: phenyl substituted internal alkyne attacking triflic anhydride activated diphenyl sulfoxide to give a sulfonium vinyl triflate intermediate, hydrolysis to give an α-sulfonium ketone, and then substitution with various nucleophiles. This method

  α-杂取代酮的合成是通过硫介导的内部炔烃的双官能化一锅法实现的。反应设计包括：苯基取代的内炔攻击三氟甲磺酸酐活化的二苯亚砜，得到乙烯基三氟甲磺酸锍中间体，水解得到α-锍酮，然后用各种亲核试剂取代。该方法提供了快速获取α-氨基酮、α-酰氧基酮、α-硫酮、α-卤代酮、α-羟基酮和相关杂环结构的统一途径。

  A very rapid, convenient, and general method for the synthesis of alpha-oxo thiocyanates has been described by using clay supported ammonium thiocyanate. The procedure avoids the use of additional catalyst, solvent, aqueous work-up and the yields are high. Moreover, the method is applicable for a variety of aryl, heteroaryl, alkyl alpha-halo carbonyls, beta-keto tosylates, alpha-halo beta-dicarbonyl, alpha-tosyl, beta-dicarbonyl, alkyl halide, and alkyl tosylates.
