First Experimental Evidence of an Intramolecular H Bond between Aliphatic Cl and Aromatic C–H

The first example of an intramolecular H bond between aliphatic Cl and aromatic C–H was observed in the crystal of <i>C</i>₂-symmetric (4<i>R</i>,5<i>R</i>)-4,5-bis(diphenylchloromethyl)-1,3,2-dioxathiolane 2-oxide. In this case one Cl atom is engaged in H-bonding with two <i>ortho</i>-C–H groups in the axial and equatorial phenyl planes, with the recorded distances of 2.562 Ǻ and 2.804 Ǻ, respectively. The observed angle for C_<i>a</i>–H–Cl is 108.41° and that for C_<i>q</i>–H–Cl is 96.53°

Copper-Catalyzed Radical Reductive Arylation of Styrenes with Aryl Iodides Mediated by Zinc in Water

A copper/aniline catalyst system enables the radical arylation of styrenes using aryl iodides mediated by zinc in water. This transformation provides an efficient synthetic methodology for the convenient synthesis of diarylethane

Figures S1 - S3 and Table S1 from <i>Bt</i> rice plants may protect neighbouring non-<i>Bt</i> rice plants against the striped stem borer, <i>Chilo suppressalis</i>

Figure S1: Key volatile compounds emitted by non-Bt rice plants (from 20:00 pm to 4:00 am) that were damaged by Chilo suppressalis larvae for 72 h (A) or remained undamaged (B). IS = internal standard. The peak numbers of all compounds are consistent with those listed in Table 1.; Figure S2: Number of eggs laid by female Chilo suppressalis on undamaged or caterpillar-damaged Bt or non-Bt rice plants (greenhouse cage experiment). Caterpillar symbols indicate damage by two 3rd instar of C. suppressalis. Each choice test was performed with 15 to 20 replicates, each consisting of a group of 10 pairs of C. suppressalis adults. The number of egg masses represents the total egg masses laid on two rice plants. Asterisks indicate significant differences: *P < 0.05; ** P < 0.01; n.s. indicates no significance (P > 0.05) (paired-sample t-test).; Figure S3: Performance of Chilo suppressalis larvae feeding on rice plants that were either undamaged or damaged by 3rd instars of conspecifics. Two-day old larvae of C. suppressalis were individually placed on caterpillar-damaged or undamaged non-Bt rice plants for 7 days. Forty insects were tested in each treatment. Asterisks indicate significant differences between the undamaged and caterpillar-damaged treatments (P<0.05).; Table S1: Volatile compounds collected from the headspace of non-Bt rice plants (PM 20:00-AM4:00) that were undamaged or damaged by Chilo suppressalis larvae for 72 h. Values under “Undamaged” and “Caterpillar-damaged” are the mean percentages ± SE of the peak area of the internal standard (nonyl acetate). Asterisks indicate significant differences between undamaged and caterpillar-damaged rice plants according to the Student's t-test (*P  0.05, **P  0.01)
