Cyclization of ortho-alkynylphenylphosphine P-ylides; dependence on ylide nucleophilicity

Publication date: Available online 27 September 2018Source: Journal of Organometallic ChemistryAuthor(s): Jing-Jing Hou, You-Zhi Xu, Zhen-Jie Gan, Xu Zhao, Zheng Duan, Francois MatheyAbstractP=CH2 ylides derived from ortho-alkynylphenylphosphines readily cyclize to give phosphindole derivatives. With a stabilized ylide such as P=CHC(O)Ph, the outcome of the reaction is completely different. The reaction proceeds at high temperature and produces phosphanaphthalenes.Graphical abstract
