WebHere we will go through the following reactions listed below to learn the mechanisms behind these electrophilic additions of alkynes: (1) HX Addition to Alkenes, (2) Halogenation of Alkynes and (3) Hydration of Alkynes. Figure 1. The addition of an electrophile to either an alkene or an alkyne will undergo the same steps listed below. WebMethyl acetylene (propyne) process [ edit] Using Reppe chemistry, methyl acetylene is converted to MMA. As developed by Shell, this process produces MMA in one step reaction with 99% yield with a catalyst derived from palladium acetate, phosphine ligands, and Bronsted acids as catalyst: [7] CH≡CCH 3 + CO + CH 3 OH → CH 2 =C (CH 3 )CO 2 CH 3
