A palladium complex sequentially promoted two mechanistically distinct reactions, the first, cyclization of 2-(alkynyl)aryl isocyanates with benzylic alcohols, and the second, [1,3] rearrangement of a benzyl group from oxygen to carbon, furnishing 3,3-disubstituted oxindoles in one pot.
钯配合物依次促进了两种在机理上不同的反应，第一，2-(炔基)芳基异氰酸酯与苄醇的环化反应，第二，苄基从氧到碳的[1,3]重排反应，一锅法得到 3,3-二取代的氧吲哚。
