A. Segundo et al., REACTIONS OF ALKYNOLS WITH (ALKYNYLALKOXYCARBENE) METAL-COMPLEXES (METAL = CHROMIUM, TUNGSTEN), Organometallics, 13(6), 1994, pp. 2467-2471
(Alkynylalkoxycarbene)metal complexes react with alkynols to give diff
erent types of products depending fundamentally on the substitution of
the triple bond (mono- or disubstituted alkynes) and the spacing betw
een the triple bond and the hydroxy functions.
