As a result, corrosion readily proceeds at the interface.
The polyaddition reactions readily proceeded in desirable yields as one-pot reactions starting from 3 without separately synthesis of the corresponding diisocyanate.
The further reaction of intermediates 1 with 80% hydrazine hydrate could proceed readily at room temperature to give intermediates 2 [27].
The subsequent electro-deposition of cuprous ions can then proceed readily and the overall faradaic efficiency, based on a 2 electron process, may reach 141%.
The values computed for the two energy barriers involved in this catalytic reaction after enthalpy correction indicate that the catalytic reaction should proceed readily at room temperature.
Our initial efforts focused on the reaction of 2- and 4- substituted phosphonates to give the relevant stilbenes and these proceed readily to completion with the use of 1.2 equivalents of potassium t-butoxide as base.
The aldol reaction of intermediate 2 with 4-aminobenzaldehyde in dry tetrahydrofuran (THF) using piperidine as a catalyst can proceed readily at 60°C to obtain intermediate 3. Subsequent treatment of intermediate 3 with acyl chloride and potassium carbonate in dry THF solvent at ambient temperature afforded the desired compounds (4a to 4v) in 40% to 70% yields.
Such studies indicate that the modest activity of Co FTS catalysts might very well be attributable to the difficulty to remove chemisorbed oxygen from the metallic surface, rather than to dissociation of CO, which was found to proceed readily at step edge sites.
We next varied the reaction solvent and obtained the best result by using MeCN (entry 4).[ 10] The reaction was found to proceed readily at room temperature in 36 h (entry 5) or in 1 h when the reaction temperature was increased to 60 °C (entry 6).
Because of the high operating temperatures (900 to 1,000 °C, or 1,600 to 1,800 °F), the electrode reactions proceed very readily.
