    “…The dynamics of this process is investigated by measuring the trapping probabilities of n‐butane, iso‐butane and 1‐butene on a set of frozen 1‐alkyl‐3‐methylimidazolium‐based ILs [C( n )C(1)Im]X, where n=4, 8 and X(−)=Cl(−), Br(−), [PF(6)](−) and [Tf(2)N](−). …”

    “…The N—C(ar­yl) bond length [1.4225 (14) Å] is inter­mediate between that in N-phenyl-tert-butane­sulfinamide [1.4083 (12) Å] and the N—C(alk­yl) bond lengths in N-alkyl­alkanesulfinamides (1.470–1.530 Å), suggesting weaker delocalization of electrons over the N atom and the aromatic ring due to the presence of the 4-meth­oxy group.…”

    “…The title Schiff base compound, C(9)H(12)N(2)O(2), was obtained from a condensation reaction of butan-2-one and furan-2-carbohydrazide. The furan ring and the hydrazide fragment are roughly planar, the largest deviation from the mean plane being 0.069 (2)Å, but the butanyl­idene group is twisted slightly with respect to this plane by a dihedral angle of 5.2 (3)°. …”
