A simple method for the preparation of allylic triflones from allenes and triflyl chloride in the presence of (EtO)2P(O)H has been developed. The features of this reaction are catalyst-free and simple starting substrates. This method tolerates diverse functional groups and substituted allylic triflones are obtained in moderate to good yields.

Direct strategies for the iodothiocyanation and iodonitration of allenes have been developed. In this process, potassium thiocyanate/silver nitrite and molecular iodine are used as the source of SCN, ONO2and iodine to provide the desired products in moderate to good yields with high stereoselectivity.

, p. 8986 - 8993 (2013/10/08)
The asymmetric addition of silylacetylenes to 1,1-disubstituted allenes proceeded in the presence of a cobalt/chiral bisphosphine ligand to give the corresponding enynes with high enantioselectivity. The results of deuterium-labeling experiments indicated
Ruthenium catalyzed C-C bond formation via transfer hydrogenation: Branch-selective reductive coupling of allenes to paraformaldehyde and higher aldehydes
Ngai, Ming-Yu,Skucas, Eduardas,Krische, Michael J.
supporting information; experimental part, p. 2705 - 2708 (2009/05/26)
(Chemical Equation Presented) Under the conditions of ruthenium-catalyzed transfer hydrogenation employing 2-propanol as the terminal reductant, 1,1-disubstituted allenes 1a-h engage in reductive coupling to paraformaldehyde to furnish homoallylic alcohol
