For the isomerization of toluene via methoxy and benzene intermediate, the similar proton activation, which results in the formation of a phenoxy intermediate, is achieved (see Figure 9). As previously, the bond between the zeolitic oxygen atom and the aromatic carbon atom stretches out. A "free" Wheland complex is eventually reached which can reorient to favor the position of the toluene methyl group with the demethylation transition state. 

Cyanoketenes are conveniently prepared - by thermolysis of 2,S-diazido-l,4-quinones or 4-azido-3-halo(or phenoxy)-5-methoxy-(5 -furan-2-ones in refluxing benzene (Scheme 5).
