Divergent Insertion Reactions of Pt–Carbenes Generated from [3+2] Cyclization of Platinum‐Bound Pyrylliums

Good fusion: We describe the reactivity of Pt–carbene B, derived from enynals 1 via A, with Pt catalysts to afford fused cyclopropanes 2, which are obtained by insertion into the CH bond of the β position. Acid‐catalyzed rearrangement of the cyclopropanes 2 smoothly occurred to form spiranes 3 (see...

Description
Summary:	Good fusion: We describe the reactivity of Pt–carbene B, derived from enynals 1 via A, with Pt catalysts to afford fused cyclopropanes 2, which are obtained by insertion into the CH bond of the β position. Acid‐catalyzed rearrangement of the cyclopropanes 2 smoothly occurred to form spiranes 3 (see scheme).
