(+)-2-Carene heated neat with iron pentacarbonyl leads to α-phellandrene-Fe(CO)3 complex ( 15 percent ), p. cymene ( 15 percent ), (-1)-(1S)-3,8,8-trimethylbicyclooct-3-ene-7-one ( 50 percent ) and (+)-(1S,7S)-3,8,8-trimethylbicyclo

The reactions of (+)-2-carene (6b) and (+)-3-carene (15) with iron carbonyls are studied under various conditions.Besides double bond isomerization and interconversion of the two isomeric hydrocarbons, at least two different modes of ring opening leading to six- and seven-membered ring products are observed.Under mild conditions the primary ring opening complex 7b is isolated without loss of sterical information.Carbonylation of 7b under various conditions yields optically active cycloheptene systems 18, 19, and 20 or the bicyclic systems 9b and 10b.
