One pot oxidative esterification of aldehyde over recyclable cesium salt of nickel substituted phosphotungstate

- Cesium salt of nickel substituted phosphotungstate synthesised by one pot method.
- Application of catalyst for one pot oxidative esterification of aldehydes.
- The superiority lies in obtaining higher selectivity for the desired ester product.
- High turn over number under sustainable reaction conditions.
- Advantage of using nickel as transition metal instead of expensive metal.
