Ruthenium(II) and iron(II) POCOP pincer complexes have readily been obtained from ligands derived the 1,3- 1,7-dihydroxynaphtalene isomers. The two ruthenium(II) isomers displayed remarkable catalytic activity for Friedländer annulation, reaction was tolerant to a wide array of electron-withdrawing -donating substituted ketones. reactions produced selectively quinoline derivatives in conversions up 99% at low catalysts loadings with turnover numbers close 1000. iron also exhibited notable activity, albeit lower than their ruthenium counterparts. These results mark significant advancement developing derivatives.

An acid or hydrogen gas-free electrochemical protocol is established for the hydrogenation of strained rings (cyclopropane and cyclobutane) at room temperature atmospheric pressure. The mechanistic study revealed that reaction was initiated via reduction carbonyl group. methodology highly specific toward such as cyclopropane cyclobutane, which exhibit broad functional group tolerance.
