A Pd(II)-catalyzed alkoxycarbonylation of aromatic C–H bonds with alkylchloroformates has been developed. A broad range of benzamides and alkylchloroformates are compatible with this protocol. The reaction is operationally simple and scalable. The direct group could be readily removed to access substituted phthalic acid esters (PAEs), 1,2-dibenzyl alcohols and phthalamides. Besides alkoxycarbonylation

The present invention discloses and claims a series of 2,3,5-substituted pyridone derivatives as defined herein. This invention also relates to methods of making these compounds. The compounds of this invention are inhibitors of poly(adenosine 5'-diphosphate ribose) polymerase (PARP) and are therefore useful as pharmaceutical agents, especially in the treatment and/or prevention of a variety of diseases, including diseases associated with the central nervous system and cardiovascular disorders.
Process for preparing aromatic isocyanates by reacting the corresponding formamides with an oxygen-comprising gas over noble metal catalysts at temperatures of from 300 to 600° C. and a contact time of from 1 to 1000 ms, wherein:
a. the formamide is vaporized before entering the reaction zone,
b. the reaction mixture obtained is quenched with an alcohol-comprising quenching liquid and
c. the urethane formed is dissociated into isocyanate and alcohol.
