The 13C NMR spectra of t-butyl formate (1), 1,1-diethylpropyl formate (2), and 2,6-dimethylphenyl formate (3) were measured at various temperatures. It was found that the signals of the trans and cis isomers in 1 and 2 are separated at very low tempe

The first 1,8-diheteroaromatic naphthalenes, 1,1′-(1,8-naphthylene)di-1H-1,2,3-triazoles (1), were synthesized by 1,3-dipolar cycloadditions of 1,8-diazidonaphthalene to acetylenic esters. The spectral properties of these compounds were studied and
