PREVIS Sulfur ylldes can be generated in a manner similar to that used to produce phosphonium ylldes. For example, treating a sulfonium salt with a strong base gives the sulfur ylide. Ph strong base S-CH₂ S-CH₂ Br Ph Ph Sulfoniu im bromide salt Sulfur ylide Sulfur yides react with aldehydes and ketones to give epealdies Draw the structure of the intermediate and the product of the reaction when this compound reacts with CHSCHU You do not have to consider stereochemistry You do not have to explicitly draw Hatoms. Do not include lone pairs in your answer. They will not be considered in the grading Draw only the structure of the intermediate and the epoxide product. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. - Separate structures using the sign from the drop-down menu PREVIS Sulfur ylldes can be generated in a manner similar to that used to produce phosphonium ylldes.
