Dipole Moments and UV Spectra of some Long-chain Molecules

About one hundred compounds with long-chain molecular structure have been prepared (most of them are new).The dipole moments of four α,ω-bis(p-methoxyphenylthio)alkanes and five α,ω-bis(p-methoxyphenylsulphonyl)alkanes have been determined to find the effect of chain-length.In the case of sulphones, the observed values are compared with the values calculated for free rotation around all bonds intervening the end dipoles.The uv spectra of some 1,2-(distyrylsulphonyl)ethanes, and a number of α,ω-bis(arylsulphonyl)- and α,ω-bis(aryloxy)alkanes have been recorded to examine the applicability of the principle of chromophore additivity.

AN UNEXPECTED ISOMERISATION OF 1,4-DIARYLOXY-2-BUTYNES TO Z,Z-1,4-DIARYLOXY-1,3-BUTADIENES-POTENTIAL DIENES FOR DIELS-ALDER REACTION

1,4-Diaryloxy-2-butynes 1 were converted to 1,4-diaryloxy-z,z-1,3-butadienes 2 in refluxing HMPA in presence of potassium carbonate.
