Ma. Kondratenko et al., PREPARATION, ISOLATION AND CHEMICAL-REACTIVITY OF THE ALPHA-CF3-PROPARGYLIUM ION STABILIZED BY A HETEROBIMETALLIC [CO-MO] CLUSTER, Journal of organometallic chemistry, 487(1-2), 1995, pp. 15-17
The synthesis of a diastereomeric alpha-CF3 derivative of a propargyli
c alcohol complexed in a hetero-bimetallic [Co-Mo] cluster is describe
d. By the action of HBF4 on the alcohol, one variety of complexed prop
argylium ion is formed.
