Decarboxylative Phosphine Synthesis: Insights into the Catalytic, Autocatalytic, and Inhibitory Roles of Additives and Intermediates

Phosphines are among the most widely used ligands, catalysts, and reagents. Current synthetic approaches to phosphines are dominated by nucleophilic displacement reactions with organometallic reagents. Here, we report a radical-based approach to phosphines that proceeds by a cross-electrophile coupling of chlorophosphines and redox-active esters. The reaction allows for the synthesis of a broad range of substituted phosphines that were not readily attainable with the present methods. Our experimental and DFT computational studies also clarified the catalytic, autocatalytic, and inhibitory roles of additives and intermediates, as well as the mechanistic details of the photocatalytic and zinc-mediated redox modes that can have implications for the mechanistic interpretation of other cross-electrophile coupling reactions.

Convenient and convergent syntheses of long-chain α,ω-dibromides and diphosphines of the formula X(CH2)nX (n = 18-32)

The known tetrahydropyranyl ethers Br(CH2)yOTHP (y = 6, 9, 11), which are easily prepared from commercial bromoalcohols, are sequentially treated with Mg, Li2CuCl4, and X(CH2)2X (z/X = 6/Br, 7/Br, 8/Br, 10/Br, 10/I) to give the diethers THPO(CH2)nOTHP in 68-40% yields (n = 2 y + z = 18, 19, 20, 22, 24, 28, 32). Subsequent reactions with Ph3P and 2,4,4,6-tetrabromocyclohexa-2,5-dienone give the title compounds Br(CH2)nBr in 91-75% yields. Reactions with commercial K+PPh2 give the diphosphines Ph2P(CH2)nPPh2 in 95-74% yields.
