A library of sixteen S-thiocarbamates was synthesized utilizing a newly discovered one-pot synthetic procedure starting from N-formamides, which omits isolation of the isocyanide intermediate. Experiments were conducted to investigate the mechanism and identify side-reactions and side-products. Finally, four norbornene-based thiocarbamates were polymerized by ring-opening metathesis polymerization

Here, we developed an efficient method for the synthesis of s-alkyl or aryl thiocarbamates catalyzed by Na2CO3 undermildconditions using alkyl or aryl isocyanates and thiophenols or thiols. In situ reaction with deuterated tetrahydrofuran (d8-THF) was carried out to investigate the reaction mechanism. This method has the advantages of high yield, good functional group tolerance and high atom economy
在这里,我们开发了一种在Na 2 CO 3催化下,使用烷基或芳基异氰酸酯和苯硫酚或硫醇在温和条件下合成S-烷基或芳基硫代氨基甲酸酯的有效方法。与氘代四氢呋喃( d 8 -THF)进行原位反应以研究反应机理。该方法具有收率高、官能团耐受性好、原子经济性高等优点。
