Demands for efficient phosphorus-element bond-forming reactions to prepare structurally sophisticated phosphorus compounds that are not readily available by classical methods have stimulated studies on new phosphorus bond-forming reactions by transition-metal catalysis.[1] While catalytic CÀP bond-forming reactions through couplings of PÀH bonds with organohalides or additions of PÀH bonds to CÀC unsaturated bonds are well known,[ ...
