Can someone give me link on some step-by-step synthesis of p-benzoquinone with H2O2/I2 method!?

2,3-Dichloro-5,6-dicyano-1,4-benzoquinone - Wikipedia

Our synthesis began with the preparation of 6 (>99% ) from 5 in 5 steps in 21.8% overall yield, as reported previously (). The diastereoselective reduction of the ketone group in 6, followed by the chemoselective methylation of the resulting alcohol, afforded 8 in 75% yield (1.0 g scale). The structure of 8 was unambiguously confirmed using X-ray crystallography. After extensive experimentation, we found that the regioselective Wacker oxidation of the substituted olefin using air as a co-oxidant gave ketone 9 in good yield. We reasoned that the methoxy group at C10 in 8 was critical for this regioselective outcome. Finally, the double elimination of the oxa-bridge in 9 proceeded smoothly using a slightly modified version of Cha’s procedure in the presence of TMSOTf and Me2EtN in DCM to complete our total synthesis of (−)-1 in 81% yield in >99% . The 1H and 13C NMR spectra of synthetic 1, as well as its optical rotation, were identical to those of the natural product.

For the application of cyclobutane derivatives in organic synthesis, see:

N2 - The palladium-catalyzed Suzuki-Miyaura coupling reaction of tetrabromo-p-benzoquinone and 2,3-dibromonaphthoquinone provide a convenient approach to tetraaryl-p-benzoquinones and 2,3-diarylnaphthoquinones. Suzuki-Miyaura of tetrabromo-1,4-phenylene bis(trifluoromethanesulfonate) and of 2,3-dibromonaphthalene-1,4-diyl bis(trifluoromethanesulfonate) resulted in the formation of the same type of quinone products instead of the expected benzene and naphthalene derivatives.

However, p-benzoquinone can be highly toxic and fatal if swallowed, inhaled or absorbed through the skin.
