Ab. Koldobsky et al., 1-Trifluoroacetyl-2-trimethylstannyl- and 1-trifluoroacetyl-2-bromoacetylenes as new dienophiles in the Diels-Alder reactions, MENDELEEV C, (3), 2001, pp. 99-100
Trifluoroacetic anhydride exotermically reacts with bis(trimethylstannyl)ac
etylene to form previously unknown 1-trifluoroacetyl-2-trimethylstannylacet
ylene, which interacts with bromine to produce 1-trifluoroacetyl-2-bromoace
tylene.
