✦ Synopsis

Red&ion of 1,3-butadiene with H,(D,) on a PI electrode in 0.5 M H,SO,(D,SO3 was studied on open circuit. Results on the reaction kinetics, the open circuit potential, the product distribution and the isotope exchange show that (1) the diiuaion of 1,3 butadiene (1,3-Q or H, controls the reaction rate according as PH/PcL > 20 or -z 20, respectively (called B or H-region), (2) in B-region, butane (C,) is a main product ( > 90 %) and produced via 1-butene (l-C,), (3) in H-region, C, (50 "/,) is also produced via l-C, and therest (SoyAis l-C+, t-andc-2-C~inaratioof66:20:14, (4) the isotopeexchangeoczursby thestepC,H,(a) + H(a)+C,H,(a)and C,Hs(a) + H(a)+C,Hg(a), (5) there are two kinds of C,H,(a);onegives I-C, and t-2-Ckand the other c-2-C; and (6) the paths from 1-C; to C, and from f-and c-2-C; to C4are different; the latter gives a more enhanced isotope exchange.
