The present invention is directed to novel cyclopropanated macrocyclic ketone and lactone compounds of the general formula
wherein X is an atom or a functional group selected from the group consisting of 0, N, S, CH, or CH
2
; wherein Y is a straight or branched hydrocarbon moiety consisting of 1 to 20 carbon atoms; wherein W is a straight or branched hydrocarbon moiety of consisting of 1 to 20 carbon atoms; and wherein O is an oxygen atom; and the use of these novel compounds in creating fragrances, and scents in items such as perfumes, colognes and personal care products.

[Cp*P(OMe)3CoCH2CH3]+ [BarF]-, generated by the addition of HBArF to Cp*P(OMe)3Co(ethene), catalyzes the oligomerization of 1-hexene to give dimers and trimers. When a deficit of the acid is used, linear alpha-olefin dimers are produced at the expense of trimeric products: e.g., 1-butene, 1-hexene, and 1-octene give 1-octene, 1-dodecene, and 1-hexadecene, respectively.
