WebThe phenyl rings are perpendicular to the central C 2 Li 2 ring. The individual dimers are arranged in an extended structure by η 6 -coordination to neighboring phenyl rings, thus creating a polymeric zigzag ladder arrangement. WebPhenyllithium or lithobenzene is an organometallic agent with the empirical formula C 6 H 5 Li. It is most commonly used as a metalating agent in organic syntheses and a substitute for Grignard reagents for introducing phenyl groups in organic syntheses. [2] Crystalline phenyllithium is colorless; however, solutions of phenyllithium are various ...

To minimize the number of stereoisomers, the resulting ring-opening product was oxidized to ketone 99 in moderate yields (64–72 %). However, with peptides the yields were slightly lower than with amino acid ester enolates [ 18 ] (Scheme 21 ). shops at marlborough barn marlborough
