Problems and exercisesCarbon Nucleophiles

1. One Grignard reagent

Show that these four compounds can be prepared from the same Grignard reagent.

Four alcohols with a cyclohex-2-en-1-yl group: 1-(cyclohex-2-en-1-yl)ethanol, (cyclohex-2-en-1-yl)methanol, 1-(cyclohex-2-en-1-yl)cyclohexanol and 2-(cyclohex-2-en-1-yl)ethanol

2. Three routes to the same alcohol

Is it possible to prepare racemic 2-phenyl-2-butanol from three different Grignard reagents?

3. Synthesis of alkenes

Show how these alkenes can be synthesized using appropriate aldehydes or ketones.

Four alkenes: cyclohexylidenecyclohexane, cyclohexene, 1-isopropenyl-3-methylenecyclopentane and 1-isopropyl-3-methylenecyclopentane
