, (2011/06/27)
A lube base oil which comprises at least one hydrocarbon compound having as the basic skeleton a structure represented by any of the general formulae (I) to (VI) and has a viscosity at ?40° C. of 40 Pa·s or lower and a viscosity index of 80 or higher, (wherein p is an integer of 1 to 10, provided that in the formulae (I) and (II), p is not 1). It satisfies the coefficient of high-temperature traction, low-temperature flowability, and viscosity index on a high level.

The codimerization of quadricyclane (QC), the valence isomer of norbornadiene (NBD), with norbornene compounds was studied in the presence of Pd(O) complexes.Codimerization of QC with norbornene, 5-methyl- and 5-methylenenorbornene, exo-tricyclo2,4>octene-6, tetracyclo2,4.03,7>nonene-8, and penta- and hexacyclic NBD dimers was carried out in the presence of PPh3-activated Pd2(DBA)3*CHCl3 to afford a new class of hexa- to nonacyclic strained hydrocarbons with exo- and endo-tetracyclo2,4.03,7>nonane fragments.
