WebAug 23, 2006 · n-Tributylphosphine was found to efficiently catalyze the α-P addition of H-phosphonates, H-phosphinates, and H-phosphine oxide pronucleophiles on alkynes bearing phosphane oxide activating moieties. The reaction leads to 2-aryl-1-vinyl-1,1-diphosphane dioxide derivatives in good yields affording a new route to P−C−P backbones. The … WebThis article is cited by 67 publications. Carolyn L.
