Experimental insights into catalytic oxidation of 1,6-hexanediol to ε-caprolactone over (p-cymene)RuCl₂(L) complexes in non-polar media

Abstract

1,6-Hexanediol (1,6-HD) oxidation to ɛ-caprolactone (ɛ-CL) was investigated using (p-Cymene)RuCl2(L) complexes with phosphine (LP1-P5) and pyridine (LN1-N5) ligands as catalysts. Despite similar Ru electron density, the activity of (p-cymene)RuCl2(LP) increases...

Pd/HAP Catalyzed Synthesis of Adipic Acid from 1,6‐Hexanediol under Aerial Base‐free Conditions

“…[11] HDO is an important precursor for the synthesis of several other industrially essential chemicals, such as adipic acid (AA) and caprolactone. [12][13][14][15] AA is used as a precursor for the synthesis of Nylon-6 and Nylon-6,6. [16,17] Moreover, AA is also used in lubricants, cosmetics, food additives, plasticizers, and polyurethanes.…”

“…THBMF can further undergo ring‐opening hydrogenolysis to form 1,2,6‐hexanetriol, which is then hydrodeoxygenated to 1,6‐hexanediol (HDO) [11] . HDO is an important precursor for the synthesis of several other industrially essential chemicals, such as adipic acid (AA) and caprolactone [12–15] . AA is used as a precursor for the synthesis of Nylon‐6 and Nylon‐6,6 [16,17] .…”
