A highly regioselective C(sp2)-P(O) cleavage of allenylphosphine oxides mediated by I2/TBHP is achieved for the first time. The divergent pathway via cleavage of (Ph)C?P(O) or (allene)C?P(O) modulated by substituents, renders the formation of 4-iodo-2-phenyl-5H-1,2-oxa-phosphole 2-oxide and α-iodoenone derivatives, respectively. A plausible mechanism through radical pathways, along with the cleavage of phenyl and diphenylphosphine oxide moieties, are verified by the trapping experiments and 18O-isotopic labeling studies.

The selenohydroxylation of readily available 1,2-allenyl phosphine oxides with PhSeCl in MeCN/H2O afforded 3-hydroxy-2-phenylselanyl-1(E)-alkenyl diphenyl phosphine oxides in good yields with very high regio- and stereoselectivities including t
