Mechanochemical Tandem Reactions: A Sustainable and Direct Route to 1,2‐Di‐Functional Indolizines via In Situ Baylis–Hillman Reaction, Cyclocondensation, Electrophilic C–H Chalcogenocyanation

Soumik Saha, B. Shravya, Truptesh T. Mulgaonkar, Saurav Bhattacharya et autres

Herein, we report a sustainable, metal‐free tandem mechanochemical strategy for the construction and C–H chalcogenocyanation of indolizines from pyridine‐2‐carboxaldehydes and α,β‐unsaturated compounds. The method involves DABCO‐catalyzed in situ formation of the Baylis–Hillman adduct followed by cyclization, delivering 2‐functionalized indolizines within 30 min …

Crystal Structures and Corrosion Inhibitions of Three Cobalt Complexes of Terephthalate Anion and Bis‐Nitrogen Donor Ligands

Hassan Hasan Hammud, Nusaybah Alotaibi, Nasreen Al Otaibi, Saurav Bhattacharya et autres

ABSTRACT Three Co(II) complexes of terephthalate anion containing 1,10‐phenanthroline (phen) or 2,2′‐bipyridine (2,2′‐bipy), are prepared. The structures of dimeric [Co2(H2O)4(μ‐H2O)2(phen)2]4+·2(C8H4O42−), 1, and the polymeric [Co2(H2O)2(phen)2(μ‐C8H4O4)2]n, 2, complexes were confirmed by single crystal structure determination. Both complexes have CoN2O4 core in a distorted …
