Platinum(II) Enyne Cycloisomerization Catalysis: Intermediates and Resting States
{{output}}
In situ generated [(PPP)Pt][BF(4)](2) (PPP = triphos) catalyzes the cycloisomerization of 1,6-enyne-ols by initiative pi-activation of the alkyne. This generates an isolable cationic Pt-alkenyl species which subsequently participates in turnover limiting proto... ...
