Alkynyl sulfoxides are important building blocks with a unique reactivity in organic chem., but only a few reliable methods have been reported to synthesize them. A novel route to access alkynyl sulfoxides is reported herein by using ethynyl benziodoxolone (EBX) reagents to trap sulfenate anions generated in situ, via a retro-Michael reaction. The reaction takes place under metal-free and mild conditions. It is compatible with aryl, heteroaryl, and alkyl sulfoxides with up to 90% yield. This practical access to alkynyl sulfoxides is expected to facilitate the application of these useful building blocks in organic synthesis. In the experiment, the researchers used 2-Iodobenzoic acid(cas: 88-67-5Product Details of 88-67-5)
2-Iodobenzoic acid(cas: 88-67-5) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Product Details of 88-67-5Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution.
