The mechanism of transformation between reactants and products can be followed using 1,3-segmatropic rearrangement and conjugated dual hydrogen bonding (CDHB) complex formation.  Journal Name : ASIAN JOURNAL OF CHEMISTRY  Volume : 14  Issue Number : 2  Publishing Year : 2002 AH   Added Date : Saturday, June 14, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email أ.د. شعيل بن احمد الثبيتي Al-Thabaiti SA Researcher     فوزية محمد النويصر Al-Nowaiser FM Researcher     Back To Researches Page
