mixtures, (arylsulfinyl)allenes give allyl alcohols (ArSO2–CR1=CH–C(OH)R2R3). Plausible reaction mechanisms have been proposed for all studied reactions.

Allenes are widely
[18], or amisulpride [19]. Substantial contribution in this area was made by Harmata et al. [20][21][22][23][24]. However, to the best of our knowledge, electrophilic reactions of (arylsulfonyl)allenes have not been widely studied yet. It has been shown by Ma et al. that ArSO2-allenes take part into
work on transformations of phosphonoallenes under the action of strong Brønsted or Lewis acids [29][30][31][32], we undertook a special study on reactions of (arylsulfonyl)allenes 2a–j and (arylsulfinyl)allenes 1a,b (Scheme 1).
