In the oxidation of polycyclophosphanes , oxygen is bound exocyclically and is not inserted into the PP bonds. The P skeleton of the educts remains intact during the oxidation. l a and its isomer, with oxygen on P3 of the five‐mem‐bered ring, and 2a and 2b are obtained from P 6 , t Bu 4 , and P,tBu, respectively. Proof of the constitution of the compounds followed from the 31 P{ 1 H}‐NMR spectra, which could be taken from an NMR handbook.
