“…Initially, under an oxygen atmosphere, the reaction of styrene (1 a) with (iPrO) 2 P(O)H (2 a) was performed to examine the catalytic activity of various transition-metal complexes including Au, Ag, Cu, Ru, Rh, Ni, Pd, Pt, Bi, In, Ti, and Fe salts (see Table S1 in the Supporting Information). Among the above-mentioned metal salts examined, copper salts, especially CuBr 2 , was found to be the most effective catalyst to generate the desired product 3 aa ( [11][12][13][14][15][16][17]. The addition of a base was critical to the success of this oxyphosphorylation reaction and no product was detected in the absence of a base.…”
