A facile synthesis of 1,2‐azidoalcohols from their epoxides using α,α',α”‐N‐hexakis(triethylammoniummethylene chloride)‐melamine as a multi‐site phase‐transfer catalyst in water was developed. By this eco‐friendly and highly atom‐economic method, a variety of 1,2‐azidoalcohols was obtained in high yields with excellent regioselectivity and in short reaction times. Application of this six‐site PTC in the ring opening of epoxides by cyanide, acetate and chloride anions was also studied. The catalyst can be recovered after completion of the reaction and can be recycled without affecting the catalytic property.

A series of new 2-(phenyl)-1, 3-and 2-(phenyl)-1,3,3-tetramethylguanidines (a-k) were synthesized by reaction of different substituted aniline and urea derivatives in the presence of phosphorus oxychloride. The yields of products following extraction from toluene without further purification were of the order of 50-70%. We have found that adjusting of the pH at 8-9 in the work up process increases the yield of products. IR, 1 HNMR, and also mass spectrscopies were used for identification of these compounds.
