In the title compound, C(36)H(44)N(4)O(4)S, the dihedral angles between the central thio-phene ring and the pendent oxadiazole rings are 12.7 (2) and 13.7 (2)°, and the dihedral angles between the oxadiazole rings and their adjacent benzene rings are 6.1 (2) and 17.5 (2)°. An intra-molecular C-H⋯O inter-action may help to establish the conformation.
α,β-Unsaturated acyl ammoniums generated from the reaction of α,β-unsaturated 2,4,6-trichlorophenol (TCP) esters bearing a pendent enone with an isothiourea organocatalyst are versatile intermediates in a range of enantioselective nucleophile-dependent domino processes to form complex products of diverse topology with excellent stereoselectivity. Use of either 1,3-dicarbonyls, acyl benzothiazol...
The experimental interfacial tension measurements of galinstan as a function applied DC voltages are presented. based on tailored, modified pendent drop setup to make it suitable for this experiment. findings rationalise Galinstan corresponding Marangoni flow that actuates under the influence change in tension, resulting from voltages. is substantiated an actuation medium enable ON or OFF state...
In the context of a random walk on an undirected graph, Kemeny's constant can measure average travel time for between two randomly chosen vertices. We are interested in graphs that behave counter-intuitively regard to constant: particular, we examine with cut-vertex at which least branches paths, regarding whether insertion particular edge into graph results increase constant. provide several t...
In this paper, we discuss the synthesis and self-assembling behavior of new copolymers derived from fatty acid/amino acid components, namely dimers of linoleic acid (DLA) and tyrosine derived diphenols containing alkyl ester pendent chains, designated as "R" (DTR). Specific pendent chains were ethyl (E) and hexyl (H). These poly(aliphatic/aromatic-ester-amide)s were further reacted with poly(et...
That stalks reorient after flowering to face upwards is a common phenomenon in many flowering plants, indicating the potential importance of fruit orientation on seed dispersal. But this idea has not been subject to an empirical test. We examined this hypothesis by analysing the evolutionary correlation between fruit orientation and other characters and by investigating the effects of fruit ori...
