The use of aldehydes as odorous materials, which can be produced through partial or total hydroformylation of cyclooctadienes, except cyclooctane aldehydes, is described. The fragrance enhancing capacity of the compounds is described in methods for their use both as perfumes and perfume enhancers or boosters.

The hydroformylation reactions of cyclopentene, cyclohexene, 4-vinylcyclohexene, cycloheptene and cyclooctene, catalyzed with a Rh(acac)2/P(OPh)3 (I) system at 80 deg C and 10 atm (CO+H2), have been studied.Only cyclopentene and 4-vinylcyclohexene undergo hydroformylation at 1 atm and 40 deg C.The hydroformylation of some cyclic dienes; (1,3- and 1,4-cyclohexadienes, 1,3- and 1,5-cyclooctadienes and 1,3-cyclopentadiene), at 10 atm and 80 deg C, was investigated in two catalytic systems: (I) and Rh(acac) (CO) (PPh3) / PPh3 (II).The main reaction products of cyclohexadienes and pentadiene (at 80 deg C, 10 atm) are unsaturated monoaldehydes.In hydroformylation of 1,5-cyclooctadiene the main product is formylcyclooctane.Key words: Rhodium; Olefins; Hydroformylation

Cocondensation of Rh atoms with cyclodienes at liquid nitrogen temperature yields Rh complexes, thermally stable in excess of the ligand, which are good catalysts for the selective hydroformylation of cyclodienes to cycloalkenecarboxaldehydes.
