An alkylate base oil of biological origin and a process to make an alkylate base oil comprising: a) hydrogenating a farnesene to make a farnesane comprising from zero to less than 5 wt % unsaturated molecules; and b) alkylating the farnesane with one or more C6 to C43 olefins in the presence of an acidic alkylation catalyst to make the alkylate base oil having a kinematic viscosity at 100° C. from 3 mm2/s to 20 mm2/s.
Synthesis of latent Grubbs-type ruthenium complex bearing a tridentate anionic bisfluoroalkoxy-carbene and unexpected formation of new complex formed upon coordination of the substrate and occurrence of only firstolefin metathesis step; triggering its activity in olefin metathesis reactions by addition of HCl.
