2- and 3-Carenes and carane have been studied by PE spectroscopy.On the basis of an analysis of orbital interactions and information obtained from the PE spectra of model compounds an assignment has been made of the bands corresponding to ionization from the molecular orbitals of the double bond and of the cyclopropane ring.

Ruthenium containing hydrotalcite (Ru-Mg-Al) is used as a solid base catalyst for >C{double bond, long}C2 and Ru-alumina for isomerization of methyl chavicol to trans-anethole. Ru-Mg-Al catalyst was reused four times without loss in its activity, however, significant loss in the conversion of methyl chavicol and selectivity of trans-anethole was observed on reusability of other ruthenium impregnated catalysts. The conversion of methyl chavicol and selectivity of trans-anethole was found to increase on increasing the reaction temperature as well as amount of catalyst. At 0.005 g catalyst amount, 55% conversion of methyl chavicol with 68% selectivity of trans-anethole was observed that increased to 93% with 82% selectivity of trans-anethole at 0.05 g catalyst amount. On further increase in the amount of catalyst to 1 g, conversion increased to 98% with 88% selectivity of trans-anethole.
Intramolecular cyclopropanation reactions of organozinc carbenoids derived from terpenoid enals
Motherwell, William B.,Roberts
, p. 1121 - 1124 (2007/10/02)
Treatment of a series of unsaturated terpenoid enals with 1,2 bis (chlorodimethylsilyl) ethane and zinc provides a simple and efficient method for intramolecular cyclopropanation.
