Twofold lithiation of dibenzofuran ( 6 ) and dibenzothiophene ( 12 ) with n ‐butyllithium/ N,N,N′,N′ ‐tetramethylethylenediamine (TMEDA) in n ‐hexane or n ‐pentane followed by the reaction with chlorodiphenylphosphine yielded the title compounds 4 and 5 , respectively, The monophosphines 4‐(diphenylphosphino)dibenzofuran ( 11 ) and 4‐(diphenylphosphino)dibenzothiophene ( 15 ) were obtained analogously via the monolithium compounds 9 and 14 of the heteroarenes. In the case of dibenzofuran ( 6 ), it was shown that mono‐ and dilithiation is controlled by temperature.
