A method for synthesizing a diynoic acid having the formula CH3(CH2)n-C≡C-C≡C-(CH2)mCO2H comprising the steps of: selecting a one-halo alkyne from the group consisting of CH3(CH2)nC≡CX, where X is a selected halogen; selecting an omega-alkynoic acid having the formula, HC≡C(CH2)mCO2H; dissolving the
A method for synthesizing a diynoic acid having the formula CH3(CH2)n-C≡C-C≡C-(CH2)mCO2H comprising the steps of: selecting a one-halo alkyne from the group consisting of CH3(CH2)nC≡CX, where X is a selected halogen; selecting an omega-alkynoic acid having the formula, HC≡C(CH2)mCO2H; dissolving the alkynoic acid in an aqueous solution of base; adding a catalytic amount of cuprous halide dissolved in an aqueous solution of alkylamine to the aqueous solution of alkynoic acid; adding a reducing agent to the solution of alkynoic acid and cuprous halide; adding the one-halo alkyne to the solution; adding as much more of the reducing agent to the solution as is necessary to maintain the cuprous ion in the cuprous state; wherein m is selected from the group of 5, 6, 7, 8, 9, 10, and 11, and n is selected from the group of 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.
