benzoxazines.' During the preparation of several of these substrates, we found that conversion of the required allylic alcohol to the bromide and 0-alkylation of 2-nitrophenol under basic conditions gave low yields of the desired products. We, therefore, sought a more direct approach involving nucleophilic substitution of an allylic alkoxide on 2-fluoro-lnitrobenzene. Nucleophilic aromatic substitution
Novel and effective calcium ionbinding molecular fluorescent probes have been developed by systematic structural modification of BAPTA ionophore. The comprehensive computational studies suggested the role of the coordination number in the chelator moiety.

activation and substitution of aliphaticalcohols. Significant efforts have focused on modifying the classic conditions to overcome problems associated with purification from phosphine-based by-products. Herein, we report a phosphine free method for alcohol activation and substitution that is mediated by sulfuryl fluoride. This new method is effective for a wide range of primary alcohols using phthalimide
