for the synthesis of P-chiralphosphine derivatives pose con-siderable challenge. Herein we present a direct Pd/Xiao-Phos-catalyzed cross-coupling reaction of easily accessible sec-ondary phosphine oxides and aryl bromides, which provides a rapid access to P-chiralphosphine oxides. The reaction proceeds efficiently with a wide array of reaction partners to deliver various tertiary phosphine oxides
