Bakır Oktoat: 2,2'arilmetilenbis(3-hidroksi-5,5-dimetil-2-sikloheksen-1-on) bileşiklerinin çabuk sentezi için ticari olarak bulunan ve ucuz bir homojen katalizör

2,2'-Arilmetilen bis(3-hidroksi-5,5-dimetil-2-sikloheksen-1-on) bileşiklerinin sentezi için pratik ve uygun bir yaklaşım, homojen katalizör olarak bakır oktoat kullanılarak gösterilmiştir. Bakır oktoat, ekonomik, ucuz ve ticari olarak bulunabilen bir katalizör olarak reaksiyon sürelerini etkin bir şekilde 16-50 dakikaya indirirken tepkime profilleri son derece temiz bulunmuştur ve su kaybetmiş ksanten heterohalkası dahil olmak üzere hiç bir yan ürüne rastlanmamıştır. Saf hedef bileşikler, basit bir work-up prosedürü ile çok iyi ve mükemmel verimlerle (%83-91) elde edilmiştir. Katalizör çözeltide geri dönüştürülmüş ve dört kere, aktivitede değişme olmaksızın kullanılabilmiştir.

COPPER OCTOATE: A COMMERCIALLY AVAILABLE AND COST-EFFECTIVE HOMOGENEOUS CATALYST FOR THE FACILE SYNTHESIS OF 2,2’-ARYLMETHYLENEBIS(3-HYDROXY-5,5-DIMETHYL-2-CYCLOHEXENE-1-ONES)

A practical and convenient approach for the synthesis of 2,2’-arylmethylenebis(3-hydroxy-5,5-dimethyl-2-cyclohexene-1-ones) was presented using copper octoate as a homogeneous catalyst. Copper octoate as an eco-friendly, low cost, and commercially available catalyst, reduced reaction times effectively to (16-50 min) while the reaction profiles were absolutely clean and no side products including dehydrated xanthene heterocycle were detected. Pure target compounds were obtained in very good to excellent yields (83-91%) via straightforward work-up procedure. The catalyst was recycled in the form of solution, up to four times, with no noticeable drop in activity.
