Palladium-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate 7a using a dimethyl malonate-BSA-LiOAc system has been successfully carried out in the presence of new chiral aminophosphine ligands such as 4 in good yields with good enantioselectivities (up to 96% e.e.).

Alkylphenylethers, ortho-lithiated in good yields, are transformed according to scheme (1) to the triarylphosphines ArPPh2, Ar2PPh and Ar3P (Ar contains in all cases an ortho-alkoxy group) (Table 1.).Hydroquinonedialkylethers can be lithiated twice, forming the compounds 102 and 103.Table 2 summarizes some arylalkylethers (71 - 101) which were lithiated; table 7 presents 12 new arylalkylethers.The syntheses of triarylphosphines with one or two bulky groups (105 - 110) and of triarylphosphines with one or two 3,4-dialkoxyphenyl groups (111 - 114) are reported.The 31P-spectra of the compounds prepared are discussed with respect to the validity of the Tolman-rule.
