The rhodium-catalyzed hydroformylation of 1-arylbutadienes derived from lignocellulosic bio-resources has been carried out in toluene and green solvents. In the presence of DPPE and XANTPHOS ligands, a regioselective Markovnikov Rh-H insertion takes place resulting in branched aldehydes in high selectivity, which contrasts with previous results obtained from aliphatic conjugated dienes. Depending on the nature of the diphosphine ligand, conjugated enals or saturated aldehydes are obtained in good to excellent selectivity. The later have a potential interest for fragrance industry, as they are homologous to commercial fragrance ingredients.

The reaction of arenediazonium chlorides with 1,3-alkadienes in the presence of iron(II) chloride was investigated.It was established that the reaction takes place with the formation of products from chloroarylation of the dienes, telomerization, and additive dimerization.A method is proposed for the synthesis of diaryloctatetraenes containing substituents in the aromatic rings and in the aliphatic chain.
