A student researched lab analysis of the synthesis of triphenylmethanol from benzophenone and bromobenzene. After the german chemist august kekulé and his belgian student antoine paul nicolas franchimont (1844–1919) first synthesized triphenylmethane in 1872, the russian doctoral student walerius hemilian (1851–1914) first synthesized triphenylmethanol in 1874 by reacting triphenylmethyl bromide with water as well as by. The goal of this experiment is to synthesize a grignard reagent phenyl magnesiumbromide, and use it to synthesize the alcohol triphenylmethanol via gr. Triphenylmethanol is an organic compound it is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene in strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable trityl carbocation.
Novel trityl type handles have been prepared and applied to solid phase synthesis using 9 - fluorenylmethyloxycarbonyl (fmoc) for na - amino protection and acid labile protecting groups for side chain protection the cleavage of the resultant ester can be carried out by using appropriate mild acidic.

Pre-lab preparation (1) write the balanced equation for the reaction that you will be carrying out, including structures of the reactant and product (2) determine the quantities of reagents in the usual way the procedure will give you the proportions figure out the masses and volumes before coming to lab (3) write the. Grignard synthesis of triphenylmethanol i background in 1912 victor grignard received the nobel prize in chemistry for his work on the reaction that bears his name, a carbon-carbon bond-forming reaction by which almost any alcohol may be formed from appropriate alkyl halides and carbonyl compounds the grignard.
Coordination c synthesis of triphenylmethano exercise we will synthesize triphenylmethanol, a white crystalline arom in and of itself not very important as an end product, but the synthet duce it is extremely important this route involves the production of a g is used to generate needed carbon-carbon bonds in the product. You will first synthesize the grignard reagent starting from bromobenzene and magnesium using ether as the solvent the reaction and thus the reagent are moisture sensitive so you will be using anhydrous ether in the second step, you will be adding your grignard reagent to benzophenone to form triphenylmethanol.
