The explanation to why phosphonium ylide reacts with aldehyde or ketone to form an alkene but a sulfonium ylide forms an epoxide has to be given. Concept introduction: Ylides: Ylides are those compounds in which a negatively charged species such as carbanion is attached directly to a heteroatom like sulfur and phosphorous. Some examples of such compounds are phosphorus ylides, sulfonium ylides, carbonyl ylides and oxonium ylides.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Does the carbonyl group first react with the ethylene glycol, in an intermolecular reaction, or with the end alcohol, in an intramolecular reaction, to form a hemiacetal? Why does it react with the alcohol it does first rather than the other one? Please do not use an AI answer.
