THE SYNTHESIS AND THE STRUCTURAL INVESTIGATIONS OF CRYPTAND [3.2.1] AND N,N′-BISFORMYL [3.2] LARIAT ETHER LIGANDS

Abstract

From the reaction of dibenzo-diaza-crown ethers, which are 17- and 18-membered rings composed of N2O3-donor type, with paraformaldehyde in benzene, the first examples of cryptand [3.2.1] type ligands have been obtained. The reaction of cryptand (2) with Pd(CH3COO)2 (mediator) in the mixture of CH2Cl2/C6H6 (1/1) led to the formation of N,N′-bisformyl [3.2] (BiBLE) lariat ether (3). The structures of cryptand and BiBLE lariat ethers have been characterized by elemental analyses, MS, FT-IR, 1H-, 13C-NMR and HETCOR spectral data. The spectral data of the compounds have also been compared with the available data of related dibenzo-diaza-crown ethers.

KRİPTAND [3.2.1] VE N,N′-BİSFORMİL [3.2] LARİAT ETER LİGANDLARININ SENTEZİ VE YAPILARININ İNCELENMESİ

Abstract

N2O3-Donor atomlarından meydana gelen 17- ve 18-üyeli dibenzo-diaza-taç eterlerin benzende paraformaldehit ile reaksiyonu sonucunda kriptand [3.2.1] türünün ilk örnekleri elde edildi. Kriptand (2)’ nin Pd(CH3COO)2 ile (mediator) CH2Cl2/C6H6 (1/1) ortamındaki reaksiyonundan N,N′-bisformil [3.2] (BiBLE) lariat eter (3) sentezlendi. Kriptand ve BiBLE lariat eter bileşiklerinin yapısı, element analizi, MS, FT-IR, 1H-, 13C-NMR ve HETCOR spektrumundan yararlanılarak aydınlatıldı ve bu bileşikler için elde edilen spektroskopik veriler, dibenzo-diaza-taç eterler için elde edilen veriler ile karşılaştırıldı.
