The vial was sealed with an aluminium crimp-top cap fitted with a septum and purged with argon. t-BuOH (1.0 mL) was added via syringe, followed by aryl iodide (0.5 mmol, 1 equiv.) (if liquid aryl iodide used) and then 1,2,3,4-tetrahydroisoquinoline (75 mL, 1.2 equiv.). The vial was irradiated at 100 °C for 5 min, then cooled to room temperature.

CV was conducted in a sealed three-neck, round-bottom flask and was performed with 100 μM MV 2+ and 6.7 mM MgCl 2 in the anaerobic glove bag. The electrodes were allowed to stabilize by scanning the potential between −0.82 and −0.55 V versus the SCEs for eight cycles with a scan rate of 5 mV/s.

These flasks are available in two standard shapes: Round-bottom flasks are shaped like a tube emerging from the top of a sphere. The flasks are often long neck; sometimes they have the incision on the neck, which precisely defines the volume of flask. They can be used in distillations, or in the heating a product.

Instead, the vials have a shallow V-shaped bottom, which allows samples to be spun at low speeds if necessary while providing a better ability for complete sample recovery. We have found that the available round bottom vials with a skirted bottom do not provide a stable free-standing vial.

An example of this system is the multiple doses vial or the plastic tablet bottle. Well–closed containers protect the product from contamination with unwanted foreign materials and form loss of contents during use. Airtight containers are impermeable to solids, liquids and gases during normal storage and use. If the container is to be opened
