资源简介：
In situ generated [(PPP)Pt][BF4]2 (PPP = triphos) catalyzes the cycloisomerization of 1,6-enyne-ols by initiative π-activation of the alkyne. This generates an isolable cationic Pt-alkenyl species, which subsequently participates in turnover-limiting protonolysis with in situ generated acid. This latter reactivity contrasts cationic Pt-alkyls, which are more difficult to protonolyze. Mechanistic studies on isolated Pt-alkenyls and deuterium labeling helped to elucidate the mechanistic details.
