Nucleophilic Addition of Phosphate to Coordinated (Arene)manganes Tricarbonyl Cations
Young Keun Chung*, Hye Kyung Bae, Il Nam Jung
[(Benzene)Mn(CO)3]+ reacts with NaP(O) (OR)2 (R = Me, Et, Ph) to give the phosphonate compound 1. Compound 1 reacts with R'Li (R = Me, Ph, nBu, tBu) to yield the isomerized compound 2 and the alkylated compound 3. [(Toluene)Mn(CO)3]+ reacts with NaP(O)(OMe)2 to give the phosphonate complexes 1-A and 1-B. Treatment of 1-A with tBuLi in THF affords complexes 3-A and 3-B with the later major. With 1-B only the complex 3-C is formed. [(Anisole)Mn(CO)3]+ reacts with NaP(O)(OMe)2 to give the phosphate complex 1-C, which on treatment with tBuLi and then H2O yields compound 3-D. After demetallation of compound 3-D, meta-tertbutyl-anisole is obtained in a reasonable yield.
