Carbolithiation of N-alkenyl ureas and N-alkenyl carbamates

open access: yesBeilstein Journal of Organic Chemistry, 2013
N-Alkenyl ureas and N-alkenyl carbamates, like other N-acyl enamines, are typically nucleophilic at their β-carbon. However, by incorporating an α-aryl substituent, we show that they will also undergo attack at the β-carbon by organolithium nucleophiles,

Improving the desorption efficiency of styrene based on inorganic inhibitor modified activated carbon

open access: yes矿业科学学报
When activated carbons containing carbon-carbon double bond reactive VOCs such as saturated styrene are thermally desorbed, it is easy to form macromolecular polymers at high temperatures to block the pores of activated carbon and reduce the adsorption ...
