NMR analysis of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene

Abstract

1H, 13C and two dimensional NMR analyses were applied to determine the NMR parameters of 2-(2',3'-dihydro-1'H-inden-1'-yl)-1H-indene. The chemical shifts of all the H- and C-atoms, as well as the appropriate coupling constants were determined and the complete NMR resonance assignments of the molecule are given. The predicted patterns of the four different H atoms of the two methylene groups of the indane structural element coincided completely with the complex patterns in the NMR spectra.

1H, 13C i dvodimenzionalna NMR analiza su primenjeni da bi se odredili NMR parametri 2-(2', 3'-dihidro-1'H-inden-1'-il)-1H-indena. Određena su hemijska pomeranja svih H- i C-atoma, kao i odgovarajuće konstante kuplovanja i dat je potpun NMR raspored. Predskazane mustre četiri različita vodonikova atoma dve metilenske grupe indenskog strukturnog elementa potpuno su se poklopile sa složenim mustrama dobijenim na NMR spektru. Derivati indena predstavljaju glavne komponente pirolitičkih ulja i NMR podaci o njima mogu biti korisni u istraživanjima okoline.
