<p>The facile synthesis of β-thioacrylates has been realized via direct three-component reactions of thiophenols, Wittig reagents, and acetyl chloride. Under transition metal-free conditions, a class of β-thioacrylates have been synthesized with fair to excellent yields via cascade C=C double bond and C(sp<a href="#cit0002" target="_blank"><sup>2</sup></a>)-S bond formation.</p
