Reactions of chloromercurio aldehydes with acylchlorides gave a variety of (Z)- and (E)-enol esters. The Z/E ratio of the enol esters is dependent on the structure of chloromercurio aldehydes but independent of that of acylchlorides. Z-Rich enol esters were prepared by acylation of 2-chloromercurio aldehydes derived from propanal, butanal, and 2-phenylethanal, while E-rich 1-acyloxy-1,3-butadiene

In the presence of catalytic amounts of a fluoride source, O-trimethylsilyl enethers undergo condensation with acyl fluorides to afford O-enesters with high yields. The intermediates and final products are pure (Z) isomers if only one double bound is in conjugation with the oxygen atom whereas (E) isomers prevail if silyl dienethers or trienethers and O-dienesters or O-trienesters are formed.
