Alkylation Friedel-Crafts hydroxyalkylation

Other reactions of allyl- and vinyl-phosphine oxides include a detailed study of their intermolecular cyclization by a Friedel-Crafts-type procedure. In certain cases, the unsaturated oxides are generated in situ from /S-hydroxyalkyl(diphenyl)-phosphine oxides. Examples are given in Scheme 12 for the oxides (54)—(56). Control of double-bond position in the products of acid treatment of the oxides (57) has been achieved by using an organosilicon substituent. Thus simple alkyl... [Pg.75]

From the same element group Ga(OTf)3 demonstrated its advantages in several synthetic applications over similar catalysts [1]. Very low catalyst loadings were enough to drive various acid-catalyzed reactions including Friedel-Crafts alkylation, hydroxyalkylation, and acylation... [Pg.223]
