While the prop-2-ynyl acetates (1) rearrange to the allenyl acetates (2) in boiling benzene containing copper(I) chloride, in the presence of silver trifluoroacetate the butadienyl acetates (3), useful in Diels–Alder reactions, are formed in high yield.

Reaction of cuprates derived from R3MgBr/CuI/LiBr (R3 = n-alkyl) with R1CCCH(O2CR2)2 (R1 = sp2 hybridised substituent, R2 = mainly Me, alkyl, Ph) provides access to allenyl esters R1R3CCCH(O2CR2) (51–88%). Such species are not accessible via rearrangement of precursor propargylic R1R3C(O2CR2)CCH.

Ester‐way to heaven: Unexpected formation of bicyclo[3.1.0]hexene 4 was the main focus of combined experimental and theoreticalstudies on the Au‐catalyzed cycloisomerization of branched dienyne 1 (see scheme), which provided better understanding of the mechanistic details governing the cyclization of enynes bearing a propargylic ester group.
