“…Low catalyst loadings of S/C = 10 000:1, as electiono fs olvents and solvent-free conditions were tested.F ull conversion was observed in most cases and, pleasingly,improved selectivity was observed, up to 98:2 in favour of cinnamyl alcohol (entries [11][12][13][14][15][16][17]. The low catalyst loading and high selectivity for the allylic alcohol comparef avourably with the best homogenous catalysts under hydrogenation conditions, for example: (Ir) S/C = 500:1, [41] (Ru) S/C = 500:1, [8] (Ru) S/C = 200:1, [42] (Ru) S/ C = 200:1, [43] (Ru) SC = 500:1, [44] (Ru) S/C = 1000:1, [45] (Fe) S/C = 200:1, [46] (Fe) S/C = 500:1, [47] (Fe) S/C = 20 000:1, [48] (Ru) S/C = 10 000:1.…”
