“…148 Trogler's catalyst also hydrates other simple unhindered linear olefins (eq 128),149 though mecha-^SR H2C 028, include H-D exchange reactions between D20 and H-C bonds,37,98,152 the photolytic splitting of water,58 and the rearrangement of strained hydrocarbons. 153 In the case of isotope scrambling reactions of weak acids with D20, it appears (from the unique selectivity noted) that late-metal complexes are not simply serving as convenient sources of OH", though the role of innerand outer-sphere mechanistic steps has not been determined unambiguously.…”
