H2s nucleophile
WebIf oxides have a lot of ring or angle strain, this makes them very reactive towards ring opening. So in this video, we'll look at the ring opening reactions of epoxides using strong nucleophiles. So in the first step, we add a strong nucleophile to our epoxide. And in the second step, we add a proton source. WebSince hydrogen sulfide (H 2 S) is a much stronger acid than water (by more than ten million fold), we expect, and find, thiols to be stronger acids …
