1. The problem statement, all variables and given/known data Find the product of each reaction 2. Relevant equations Butanal (http://www.chemspider.com/Chemical-Structure.256.html?rid=e530204e-5d67-41a8-88e9-fc8e0ffcf41b), reacted first with bromobenzene (http://www.chemspider.com/Chemical-Structure.7673.html?rid=9d9b30cd-5d16-4f10-a320-9b2a445fef1f) then in acid (H3O+) Bromophenylmagnesium (http://www.chemspider.com/Chemical-Structure.10254417.html) with cyclohexylethyne (http://www.chemspider.com/Chemical-Structure.63448.html) in diethyl ether 3. The attempt at a solution I'm really not sure where either go, as neither of them seem to be a standard Grignard reagent reaction. The first is missing an Mg between the carbon group and the halogen, and the second is missing both a carbonyl (C=O) and acidic conditions. Are there alternatives to the standard reaction?
