Is Benzyltriphenylphosphonium chloride a Ylide?
In this experiment, benzyltriphenylphosphonium chloride is the nucleophile and 9-anthraldehyde is the electrophile. Sodium hydroxide is used to deprotonate benzyltriphenylphosphonium chloride to form the ylide. The solvent system in this experiment is multi-phase in nature.
Why is NaOH used in Wittig reaction?
In the second step, a base, such as sodium hydroxide (NaOH) or butyl lithium (BuLi), is used to deprotonate and forms the ylide (Wittig reagent). The ylide is used in the Wittig reaction. The ylide then acts as a nucleophile and adds to the carbonyl carbon. The overall reaction is given below.

What is the E stereoisomer of cinnamaldehyde?
(E)-cinnamaldehyde is the E (trans) stereoisomer of cinnamaldehyde, the parent of the class of cinnamaldehydes. It has a role as a hypoglycemic agent, an EC 4.3.1.24 ( phenylalanine ammonia -lyase) inhibitor, a vasodilator agent, an antifungal agent, a flavouring agent, a plant metabolite and a sensitiser.
What is the use of cinnamaldehyde?
Cinnamaldehyde is also known as a corrosion inhibitor for steel and other ferrous alloys in corrosive fluids. It can be used in combination with additional components such as dispersing agents, solvents and other surfactants. Concentrated cinnamaldehyde is a skin irritant, and the chemical is toxic in large doses,…
