Reaction Conditions:

with hydrogen in methanol at 20; under 150.015 - 900.09 Torr; for 0.005 h;Inert atmosphere;Schlenk technique;Green chemistry;

Steps:

2.3 Catalytic reactions under continuous flow

General procedure: In a typical experiment, a deaereated solution of alkyne in methanol (0.1M) was allowed to flow through the PdMonoBor column catalyst (29mg, reactor volume 176 μL) at 0.2mLmin^-1 together with a H₂ flow of 1.3mLmin^-1 at r.t. This resulted in a H₂ pressure at the reactor inlet of ca. 1.2bar (corresponding to a H₂/alkyne molar ratio of ca. 2.8), while the hydrogen gas was released at atmospheric pressure at the outlet of the reactor. Therefore, the pressure drop generated by monolithic reactor was ca. 0.2bar. The attainment of the steady-state conditions (ca. 1h) was taken as the reaction start time. The reaction was typically monitored for 14h time-on-stream by periodically analyzing the product solution for conversion and selectivity by GC, while 5.0mL aliquots were sampled at 1h intervals for Pd leaching determination by ICP-OES. The amount of Pd in solution was below the detection limit in each sample (0.006ppm).
