The reaction of activated phenoliccompounds, 2,4,6-triaryloxy-1,3,5-triazine (aryl-triazine ethers), with various isocyanates or carbodiimides in the presence of a nickel pre-catalyst resulted in the synthesis of aryl amides in good to excellent yields.

A novel oxygen-centered radical addition between acyl peroxides and isocyanides has been developed. A diverse collection of valuable arylcarboxyamides were easily synthesized by this protocol. From the preliminary mechanistic study, the elimination of carbon dioxide affords the product via an intramolecular rearrangement.
A compound of the formula:
wherein
Ar is optionally substituted phenyl, etc. ; n is 0, 1 or 2;
R1 is hydogen atom, optionally substituted alkyl, etc. ; R2 and R3 are independently optionally substituted alkyl, etc. ;
R4 and R5 are independently hydrogen atom or optionally substituted alkyl; R6 is hydrogen atom, hydroxy or alkyl;
or a pharmaceutically acceptable salt thereof is useful as a medicament for treating retinal degenerative disorders and the like.
