✦ Synopsis

The coupling reaction of 2-isopropenylpyridine with 1,5-hexadiene via C-H bond activation gave different products depending on the iigands: triphenyiphosphine as a ligand led to the cyclized products and trimethylphosphite to the Markovnikov addition product.

## Abstract Rhodium‐catalyzed hydroformylation of 1,5‐hexadiene to dialdehydes was investigated in compressed CO~2~ and in toluene using different fluorinated phosphane compounds as ligands at a temperature of 60 Β°C. Product yields depend greatly on the ligand used and, of the ligands examined, tri
