Ni-catalyzed Arbuzov reaction of 2-bromo-1H-indene with P(OEt)3, was found to be a convenient starting material for the synthesis of 2-H2P-substituted indene. 1H-Inden-2-yl(phenyl)phosphine, prepared via the Pd-catalyzed arylation of 2-H2P-substituted indene by PhI, turned out to react with 2-bromo-1H-indene in the presence of Pd(PPh3)4 and Et3N to form di(1H-inden-2-yl)(phenyl)phosphine in almost
