Compound 50‚ like its known analogue 3‚ involves an α‚β-unsaturated ketone‚ an acid-sensitive reactant‚ which prevents its direct synthesis in presence of protic solvents by refluxing. Despite of this characteristic‚ 50 was formed smoothly in 5 minutes by grinding chemistry‚ solely as E-isomer‚ without any evidence of decomposition after 1H and 13C MNR analysis. This synthetic approach provides easy access to such α‚β-unsaturated N-acylhydrazones‚ which are building blocks in the synthesis of nitrogen-containing

Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or
