Different reactivity of phosphorylallenes under the action of Brønsted or Lewis acids: a crucial role of involvement of the P=O group in intra- or intermolecular interactions at the formation of cationic intermediates

3-Methylbuta-1,2-dien-1-ylphosphonic acid derivatives (phosphorylallenes) [X(2)(O=)P–CR=C=CMe(2), X = Cl, OMe, NR(2), or SAr] undergo intramolecular cyclization into the corresponding 1,2-oxaphospholium ions in the Brønsted superacid TfOH. These cations have been thoroughly studied by means of NMR s...
