I'm having trouble with the following set of reactions and their products.
Product A is achieved by exploiting the unique aromaticity of cycloheptatriene cations. When A is treated with the Grignard reagent $\ce{MeMgI}$, a mixture of B and C is obtained. Treating A with catalytic amount of $\ce{HCl}$ in $\ce{CCl_4}$ furnishes isomer A’, which is again converted into a mixture of B and C upon treatment with Lewis-acidic Grignard reagents.
For A I got the following structure, since I could not figure out how the aromaticity of the first structure is affecting the reaction.
This cannot be correct, since the grignard reaction would produce only one product and not a mixture of two.
Having done some reasearch online on the resonance structures of cycloheptatriene, I thought of the following structure for A. But this would not produce two different products either if I am not mistaken.
