, p. 8777 - 8782 (2021/11/17)
An efficient approach via catalytic electrophilic thiocarbocyclization of allenes to construct indene-based sulfides with excellent regioselectivities is disclosed. The reactions were carried out at low temperatures by selenide catalysis in the presence o

A highly efficient method for the synthesis of tri-aryl-substituted allenes has been developed through Cu(I)-catalyzed coupling of diaryldiazomethanes with terminal alkynes. The reaction is under mild conditions and uses simple and inexpensive CuI as the catalyst. Mechanistically, the reaction follows a pathway involving Cu(I) carbene migratory insertion.
Coupling of n-tosylhydrazones with terminal alkynes catalyzed by copper(i): Synthesis of trisubstituted allenes

experimental part, p. 1114 - 1117 (2011/04/16)
The easy way to allenes: An operationally simple reaction under mild conditions has led to the direct formation of trisubstituted allenes (see scheme; Ts=4-toluenesulfonyl). An unprecedented copper-carbene migratory insertion process seems to take place,
FORMATION OF ALLENYL CATIONS BY PHOTOLYSIS OF TRIARYLCHLOROALLENES
Kitamura, Tsugio,Miyake, Sumiya,Kobayashi, Shinjiro,Taniguchi, Hiroshi
, p. 929 - 930 (2007/10/02)
Irradiation of triarylchloroallenes in methanol afforded 1,3,3-triaryl-3-methoxypropynes, suggesting the intervention of triarylallenyl cations.Irradiation of triphenylchloroallene in ethanol and 2-propanol gave the similar results but the irradiation in
CUMULENE PHOTOCHEMISTRY: PHENYL AND HYDROGEN MIGRATION IN PHENYLALLENE PHOTOREACTIONS
Klett, Michael W.,Johnson, Richard P.
, p. 2523 - 2526 (2007/10/02)
Photoreactions of tetra- and triphenylallene and 1,3,3-triphenylcyclopropane in hydrocarbon solvents are reported.Intermediacy of vinylcarbenes is supported by independent generation experiments.
