Graphical Abstract
A platinum cyclopropyl carbene complex, formed by anti attack of the furan ring on an (η2-alkyne)platinum complex (see scheme), is the key intermediate in the intramolecular reaction of furans with alkynes according to experimental studies and density functional calculations.

- 7 The reaction of 7 with AuCl3 as catalyst afforded exclusively phenol 8 (69 %).[3] In the platinum(II)-catalyzed reaction, traces (ca. 1 %) of a phenol tentatively assigned as 1,3-dihydro-6-methyl-5-isobenzofuranol were also obtained.

- 8a The calculations were performed with Gaussian 98.[8b] The geometries of all complexes were optimized at the DFT level of theory with the generalized gradient approximation and the B3LYP hybrid functional.[8c, d] The standard 6-31G(d) basis set was used for C, H, O and Cl, and the default LANL2DZ pseudorelativistic potential and basis set were used for Pt. Harmonic frequencies were calculated at B3LYP level to characterize the stationary points and to determine the zero-point energies (ZPE). The starting approximate geometry for the transition states (TS) were located graphically;
