Ruthenium catalysts Lewis base-promoted

Another type of C-C coupling reaction between tertiary and primary alcohols has been carried out with RuCl2(PPh3)3 as ruthenium catalyst and Bp3.0Et2 as Lewis acid promoter (Scheme 48) [54]. Secondary alcohols were formed in very good yields, especially when the quaternary centre of the tertiary alcohol was connected to two aromatic groups. In many cases almost perfect diastereos-electivity in favour of the syn-stereoisomer was obtained. The proposed mechanism is based on dehydration of the tertiary alcohol and formation of a carbon-centred... [Pg.222]
