HCID 755692-CarbomethoxypyridineYield 29%

Procedure

1 g of the complex MoO5 (picolinate]- [H3O]+ was dissolved in 10 ml of methanol and stirred at room temperature for one hour. 0.4 g of a bright yellow solid precipitated from solution at this time and a yield of 29% was obtained. Analysis calculated for MoO9N2C13H12 : C, 35.78%; H, 2.78%; N, 6.42%; O [active], 14.75%; Mo, 22.00%. Found: C, 35.79%; H, 2.90%; N, 6.26%; O [active] 14.11%; Mo, 22.23%. Infrared analysis: [CO]=1745 cm-1 [strong], 1680 cm-1 [strong]; [O--O]=845 cm-1 [strong], 855 cm-1 [strong]; [Mo=O]=945 cm-1 [strong]. Nuclear magnetic resonance [C5ND5 ]: 4.40, singlet, 3H, [C(O)OCH3 ]; 8.2-10.4, multiplet, 8H, [C6H4NCO2 ].
