A number of conjugate diacetylenic 1, 6-amino alcohols, RIRaC (NRaRR')-kCkC-C (OH) RsRR', and diacetylenic 1, 6-diamines, RlR $ C (NR~ R4)-kC-C% CC ( NR8R4) R1R*, were prepared by oxidative coupling reactions. The products absorbed three moles of hydrogen rapidly (with Raney nickel in ethanol), the fourth mole slowly. Hydrogenolysis, particularly of the carbon-nitrogen bond, occurred extensively where steric hindrance waa severe.
