Give the balanced equation, theoretical yield, and mechanism for the following experiment involving Wittig reaction. Please answer fully thanks
P-CH CH CH Cinnamaldehyde + cis,trans + P-O trans,trans-1,4-Diphenyl-1,3-butadiene Triphenylphosphine oxide Experiment 41C provides an alternative green chemistry method for prepar- ing 1,4-diphenyl-1,3-butadiene by the Wittig reaction. No solvent is used in this experiment. Instead, the starting materials are ground together with potassium phosphate in a mortar and pestle. This experiment wil demonstrate to students a more environmentally friendly method for carrying out a reaction that might be performed on a larger scale in industry The reaction will be accomplished by grinding cinnamaldehyde with benzyl- triphenylphosphonium chloride and potassium phosphate (tribasic, KPO). This is done using a mortar and pestle. TLC will be used to analyze the crystallized trans, trans-1,4-diphenyl-1,3-butadiene product, as well as the filtrate from the crystal- lization procedure that contains both the cis,trans and trans,trans-1A-diphenyl-1,3- butadiene isomers
