Catalytic Cyclization of o-Alkynylbenzaldehyde Acetals and Thioacetals. Unprecedented Activation of the Platinum Catalyst by Olefins. Scope and Mechanism of the Reaction [J. Am. Chem. Soc. 2004, 126, 1542315430]. Itaru Nakamura, Gan B. Bajracharya, Huanyou Wu, Kengo Oishi, Yuya Mizushima, Ilya D. Gridnev,* and Yoshinori Yamamoto* In this report, we describe cyclization of o-alkynylbenzaldehyde thioacetals catalyzed by PdI2. Recently, however, we have found a few publications closely related to this reaction. Rearrangement of ortho-palladated arylthioacetals was reported (Vicente, J.; Abad, J.-A.; Herna´ndez-Mata, F. S.; Jones, P. G. Organometallics 2001, 20, 1109. Vicente, J.; Abad, J.-A.; Herna´ndez-Mata, F. S.; Jones, P. G. J. Am. Chem. Soc. 2002, 124, 3848. Vicente, J.; Abad, J.-A.; Herna´ndez-Mata, F. S.; Rink, P. G.; Jones, P. G.; de Arellano, M. C. R. Organometallics 2004, 23, 1292). Unfortunately, these references were not included in our publication, and we are grateful to Professor Jose´ Vicente for bringing these to our attention.
