The coupling of acetals with various alkynes was achieved using only 1 mol% of inexpensive and mild Lewis acid ZnCl2, which furnished propargyl ethers. The coupling was catalyzed by Zn(OMe)Cl, which was generated in situ to form an alkynylzinc species. This protocol was allowed to expand to a one-pot subsequent reaction with allylchlorosilane to obtain a 1,4-enyne product.

(ACEs) with different cyclic substituents (cyclopentyl, furyl, and phenyl groups) were synthesized. These three liquid ACEs have different viscosities and refractive indices. After curing with anhydride, the cured ACEs show elevated glass transition temperature of up to 189 °C, and superior tensile strengths of up to 71 MPa. Interestingly, the dangling groups attached to the acetal bonds have a significant
