Different amount of boron-modified Ni/Mo2C were synthesized, characterized and tested during the hydrogenation of alkali lignin, to evaluate the effect of boron on the Ni promoted behavior. xB–Ni/Mo2C (x = 0.5, 1, 3, 5) is found to enhance the lignin conversion and bio-oil yield at the same time, and the highest bio-oil yield was obtained with 1B–Ni/Mo2C (63.8%), under the optimum reaction condition...
A series of Cinchona alkaloids derived organocatalysts have been developed and evaluated in the direct asymmetric intermolecular aldol reaction of 4-nitrobenzaldehyde and cyclohexanone. The catalyzed reactions of various aldehydes and ketones gave the corresponding aldol products with moderate to high enantioselectivities (up to 92%) and diastereoselectivities (up to >99/1, anti/syn) in the presence...
