such phosphorylallenes under the action of Brønsted or Lewis acids. Apart from that, the reaction of dichlorophosphorylallenes with arenes and AlCl3 led to products of hydroarylation of the allene system, phosphoryl-substituted alkenes and/or indanes. This is the first example of a Lewis acid-promoted
; oxaphospholium ions; phosphorylallenes; phosphoryl group; triflic acid; Introduction
Electrophilic reactions of allenes have been intensely explored in organic synthesis [1][2][3]. In particular, reports on electrophilic activation of phosphorylallenes are numerous [4][5][6][7][8][9][10]. Miscellaneous
