Data for the following three liquids are used for the analysis in Figs. 1-4 of the paper: tetramethyltetrahpenyl-trisiloxane (DC704), 5-polyphenyl-4-ether (5PPE), tripropylene glycol (TPG). In this supplementary we also include data for triphenyl phosphite (TPP), dibutyl phthalate (DBP), diethyl phthalate (DEP), and 2,3-epoxy propyl-phenyl-ether (2,3-epoxy). A summary of relevant information ab...

The title compound, C(24)H(26)N(2)O(8), was synthesized by the cyclo-addition reaction of methyl 2-phenyl-acrylate, diethyl 2-amino-malonate and 4-nitro-benzaldehyde. The pyrrolidine ring exhibits an envelope conformation. The two benzene rings are located on opposite sides of the pyrrolidine ring and subtend a dihedral angle of 59.16 (14)°. The crystal packing is stabilized by N-H⋯O and weak C...

The title compound, C23H29N3O, was synthesized from the condensation reaction of 8-hy-droxy-julolidine-9-carbaldehyde and N,N-diethyl-p-phenyl-enedi-amine. The hy-droxy group forms a intra-molecular hydrogen bond to the imine N atom and generates an S(6) ring motif. The conformation about the C=N bond is E, and the aromatic ring of the julolidine moiety is inclined to the benzene ring by 3.74 (...

BACKGROUND Buprofezin has been used for many years to control Nilaparvata lugens (Stål). Assessment of susceptibility change in the insect is essential for maintaining control efficiency and resistance management. RESULTS Eleven-year surveys showed that most field populations were susceptible before 2004. However, substantially higher levels of resistance (up to 28-fold) were found in most of...

Selective deprotection of 4-(alkoxysilyl)benzaldehyde diethyl acetals 1a-1c in the two-solvent system of hydrochloric acid and chloroform gave 4-(alkoxysilyl)benzaldehydes 2a-2c in good yields. Under these conditions, undesired hydrolysis of the alkoxysilyl group was minimized. The reaction of benzaldehydes 2a and 2b with pyrrole in the presence of boron trifluoride diethyl etherate led to 5,10...

In the mol-ecule of the title thio-ester, C(14)H(12)O(2)S, the dihedral angle between the phenyl and benzene rings is 71.8 (3)°. The meth-oxy group is essentially coplanar with the benezene ring to which it is bonded, with an r.m.s. deviation of 0.0065 (5) Å for the non-H atoms involved. In the crystal, weak C-H⋯π inter-actions are present.

In the title compound, C(13)H(10)OS, the phenyl rings are inclined to one another by 51.12 (8)°. There is a short C-H⋯S contact in the molecule.In the crystal, molecules are linked via C-H⋯O hydrogen bonds forming chains along the a axis. Molecules are also linked by C-H⋯π and weak π-π interactions [centroid-centroid distance = 3.9543 (10) Å].
