    • 3-Methyleneisoindolin-1-one derivatives are an important class of heterocycles. In fact, several molecules incorporating the 3- methyleneisoindolin-1-one core have shown interesting pharmacological activities; for recent examples, see: W.M. Abdou, R.E. Khidre, and R.F.

    • N-substituted 2-ethynylbenzamides 1 were easily prepared from commercially available 2-iodobenzoic acid through conversion into the corresponding acyl chloride followed by amidation with the suitable amine, Sonogashira coupling with trimethylsilylacetylene and deprotection, as reported in the literature: A.

    • These conditions (32 atm of CO together with 9 total atm of air, considering that the autoclave was loaded under 1 atm of air) corresponded to 78.0% of CO in air and were outside the explosion limits for CO in air (ca. 16-70% at 18-20 °C and atmospheric pressure, 14.8-71.4% at 100 °C and atmospheric pressure. At higher total pressure, the range of flammability decreases: for example, at 20 atm and 20 °C the limits are ca. 19 and 60%. See: C.M. Bartish, and G.M. Drissel M. Grayson, D. Eckroth, G.J.
