experimental part, p. 6308 - 6315 (2011/09/19)
A large series of bulky 1,2-dialkoxy- and 1,2,3-trialkoxy-benzenes was efficiently prepared via Williamson etherification. Preparation of their contiguous bromine-containing derivatives was also achieved.

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.
