In an article，Which mentioned a new discovery about 31886-57-4

Treatment of the alpha-dimethylamino[3]ferrocenophane system 3 with methyl iodide followed by dimesitylphosphine (Mes2PH) gave the alpha-(dimesitylphosphino)[3]ferrocenophane 5. This forms a frustrated Lewis pair [5/8] with B(C6F5)3 (8) that rapidly reacts with dihydrogen under ambient conditions to probably give the phosphonium cation/hydrido borate anion salt [5-H+/H-8-]. This, however, is unstable under the applied reaction conditions with regard to replacement of the newly formed phosphonium leaving group at the ferrocenophane a-position for hydride from the [HB(C6F5)3 -] counteranion to eventually yield the unfunctionalized [3]ferrocenophane product (10) and Mes2PH· B(C 6F5)3 (11) – both characterized by independent syntheses. Analogously, Ugi’s amine (6) was converted to (1-(dimesitylphosphino) -ethyl)ferrocene (7). The frustrated pair [7/8] consumes dihydrogen under similar conditions to yield the reduction products ethylferrocene (14) and Mes2PH · B(C6F5)3 (11).

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 31886-57-4. Computed Properties of C14H19FeN
