In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called A highly efficient procedure for 3-sulfenylation of indole-2-carboxylates, published in 2004-03-04, which mentions a compound: 67929-86-6, mainly applied to indole carboxylate sulfenylation; thioindole preparation; amide indol preparation cyclization; thiazepinoindolone preparation, Application of 67929-86-6.
A highly efficient one-pot procedure for 3-sulfenylation of 2-carboxyindoles is described. Treatment of thiols with N-chlorosuccinimide at -78 °C in CH2Cl2 affords sulfenyl chlorides in situ that readily react with 2-carboxyindoles to give 3-thioindoles in high yields. This new method is milder, produces less waste, and is compatible with a wide range of thiol and indole functionality.
After consulting a lot of data, we found that this compound(67929-86-6)Application of 67929-86-6 can be used in many types of reactions. And in most cases, this compound has more advantages.
