The asymmetric unit of the title compound, [Mo(2)(η(5)-C(5)H(5))(2)(C(22)H(29)P)(2)(CO)(4)]·2C(4)H(8)O, contains two half-mol-ecules of the organometallic species and two solvent mol-ecules. Both organometallic mol-ecules are completed by crystallographic inversion symmetry, yielding dimeric units with Mo-Mo single-bond lengths of 3.2703 (6) and 3.2548 (6) Å. Each Mo atom is also coordinated by...
A Cu-doped zeolite ZSM-5 (Cu-ZSM-5-M) with a micro-meso-macroporous structure was directly synthesized, and it exhibits excellent catalytic activity and good recyclability in the cross-coupling of aryl halides with diphenyl disulfides. This feature should be attributed to the structural characteristics of meso-macropores and homogeneous dispersion of active Cu(δ+) (δ < 2) species in Cu-ZSM-5-M.
In the title compound, C(17)H(14)NPSe, the P atom has a distorted tetra-hedral environment resulting in an effective cone angle of 163°. In the crystal, C-H⋯Se/N/π inter-actions are observed.
In the mol-ecule of the title compound, C(22)H(23)NO, there are two chiral atoms (R* for the C atom attached to the OH group and S* for the C atom attached to the phenyl ring). In the crystal, neighbouring mol-ecules are connected into a chain along the b axis by N-H⋯O hydrogen bonds.
Chemical investigation of the 1-BuOH soluble fraction of the dried fruits of Myrsine seguinii (Myrsinaceae) led to the isolation of five new glycosides, named myrseguinosides A-E (1-5), together with eight known compounds (6-13). The absolute structures of the new glycosides were elucidated by spectroscopic and chemical analyses to be a monoterpene glucoside (1), two flavonol glycosides (2, 3),...
