Bhanderi, Khushboo published the artcileNonconventional driving force for selective oxidative C-C coupling reaction due to concurrent and curious formation of Ag0, Product Details of C11H16O2, the main research area is phenol silver ammonia complex catalyst regieoselective oxidative coupling; biphenyl preparation.
Herein, reduction of [Ag(NH3)2]+ to Ag0 with concurrent oxidation of different phenols/naphthols to biphenyls was undertaken. The work was originated during careful observation of an undergraduate experiment-Tollen’s test-where silver mirror film deposition takes place on the walls of borosilicate glass test tube. When the same reaction was carried out in polypropylene (plastic-Eppendorf) tube, aggregation of Ag0 leading to floating Ag-particles was observed but not silver film deposition. This prompted to carry out challenging cross-coupling reaction by only changing the surface of the reaction flask from glass to plastic to silicones. Surprisingly, good selective oxidative homo-coupling on Teflon surface while cross-coupling in Eppendorf vial was observed Thus, the formation of biphenyl is driven by the macroscopic growth of Ag0 into [Ag-particle] orchestrated by Ag…Ag cohesive interaction was proposed. To validate results, experiments were also performed on gram scale. More importantly, oxidation of β-naphthol carried out in quartz (chiral) tube which yielded slight enantioselective excess of BINOL.
