p-甲苯磺酰氰是一种缺电子腈。它与环已烯酮的硅烯醇醚进行杂原子Diels-Alder反应，生成水解敏感性 [4+2]加合物。它还可与叠氮化物进行温顺[2+3]环加成反应，生成5-磺酰基四唑。p-甲苯磺酰氰也可以在存在1,8-二氮杂双环[5.4.0]十一碳-7-烯 (DBU) 或1,4-二叠氮双环[2.2.2]辛烷 (DABCO) 的情况下与醇类反应生成亚磺酸盐。 应用 p-甲苯磺酰氰可用于：多官能腈的制备；B-烷基儿茶酚硼烷的自由基氰化；通过与1,3-双硅烯醇醚进行杂原子Diels-Alder反应合成4-羟基吡啶 p-Toluenesulfonyl cyanide is an electron-deficient nitrile. It undergoes hetero-Diels-Alder reaction with silyl enol ether of cyclohexenone to yield hydrolytically sensitive [4+2] adduct.It also undergoes facile [2+3] cycloaddition reaction with azides to form 5-sulfonyl tetrazoles. p-Toluenesulfonyl cyanide also reacts with alcohols in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) or 1,4-diazabicyclo[2.2.2]octane (DABCO) to yield sulfinates. Application： Tosyl cyanide is a compound used as a cyanating and acylating agent in synthetic chemistry. Tosyl cyanide is also used as a reagent to synthesize cyanobutadiyne, a linear compound that is naturally found in various interstellar molecular clouds.
