- Indole synthesis based on a modified koser reagent
-
A new metal-free method for the rapid and productive preparation of indoles has been developed. This process is based on sterically congested hypervalent iodine compounds of the family of Koser reagents, and iodosobenzene in combination with 2,4,5-tris-isopropylbenzene sulfonic acid provides the highest yields and fastest reaction times. This reagent alone promotes the chemoselective oxidative cyclization of 2-amino styrenes to indoles in high yields under mild conditions. Convenient route to indole: A fast, productive, and operationally simple indole synthesis was developed.

- Process for the preparation of N,O-disubstituted urethanes suitable as a starting material for the preparation of isocyanates
-
A process for the preparation of N,O-disubstituted urethanes. Primary amines and alcohols are reacted with organic compounds having carbonyl groups at 120° to 350° C. Suitable carbonyl-containing compounds include N-unsubstituted urethanes. N-mono-substituted, N,N'-disubstituted ureas, or polyureas may be used in combination with the N-unsubstituted urethane. The product urethanes are particularly suitable for the preparation of isocyanates.
