Abstract
Treatment of the product from the Diazo-Coupling reaction of p-alkylaniline with 1,3-dibromopropane in THF affords intermediate compounds n-CnH2n+1AzoO(CH2)mBr. Subsequent treatment of these intermediate with thiourea in ethanol at reflux temperature leads to the desired azobenzene derivatives, n-CnH2n+1AzoO(CH2)mSH (n=4,6,8,10,12; m=3,5), in good yield. The structure data of these new compounds was presented in detail.
