Plant growth regulating properties of some substituted malonyl monoanilides. Shindo, Noboru; Kato, Masashi (Fac. Agric., Meiji Univ.Some chemicals with cas registry numbers like 36239-09-5 are also used., Tokyo, Japan). Meiji Daigaku Nogakubu Kenkyu Hokoku, (63), 41-58 (Japanese) 1984. CODEN: MDNHA3. ISSN: 0465-6083. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 25 Malonyl monoanilides I (R = R1 = H, halo, alkyl, alkoxy), prepd. from Et malonyl chloride [36239-09-5] and a substituted aniline, have plant growth-regulating activity in rice, cucumber, and lettuce, depending on their structure. The growth-regulating activity bioassays were: root elongation of rice seedlings (in vitro); lettuce germination (in vitro); root elongation inhibition in cucumber. I ( R = H; R1 = H, 2-Cl, 2-Me, 2-MeO, 4-Cl, 4-Me, 4-MeO) showed good activity at 5 and 20 ppm towards rice root elongation. As for the lettuce test, I (R = H, R1 = 2-Cl and R = 2-Me, R1 = 4-Me) showed good activity. I (R = H; R1 = 4-Me, 4-MeO, 4-I) increased the no. of tillers in rice. I had no herbicidal activity. .

Supramolecular fullerene chemistry: a comprehensive study of cyclophane-type mono- and bis-crown ether conjugates of C70. van Eis, Maurice J.; Seiler, Paul; Muslinkina, Liya A.; Badertscher, Martin; Pretsch, Ernoe; Diederich, Francois; Alvarado, Robert J.; Echegoyen, Luis; Nunez, Ignacio Perez (Lab. Organische Chemie, ETH-Hoenggerberg, Zurich, Switz.). Helvetica Chimica Acta, 85(7), 2009-2055 (English) 2002 Verlag Helvetica Chimica Acta. CODEN: HCACAV. ISSN: 0018-019X. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) The covalently templated bis-functionalization of C70, employing a bis-malonate tethered by an anti-disubstituted dibenzo[18]crown-6 (DB18C6) ether, proceeds with complete regiospecificity and provides two diastereoisomeric pairs of enantiomeric C70 crown ether conjugates, featuring a five o'clock bis-addn. pattern that is disfavored in sequential transformations. The identity of these conjugates was revealed by X-ray crystal-structure anal. With a bis-malonate contg. a syn-disubstituted DB18C6 tether, the regioselectivity of the macrocyclization via double Bingel cyclopropanation changed completely, affording two constitutionally isomeric C70 crown ether conjugates in a ca. 1:1 ratio featuring the twelve and two o'clock addn. patterns, resp. The X-ray crystal-structure anal. of the twelve o'clock bis-adduct revealed that a H2O mol. was included in the crown ether cavity. Two sequential Bingel macrocyclizations, first with anti-DB18C6-tethered bis-malonate and subsequently with syn-DB18C6-tethered bis-malonates, provided access to the first fullerene bis-crown ether conjugates. The two diastereoisomeric pairs of enantiomers were formed in high yields and with complete regioselectivity. The cation-binding properties of all C70 crown-ether conjugates were detd. with the help of ion-selective electrodes (ISEs). Mono-crown ether conjugates form stable 1:1 complexes with alkali-metal ions, whereas the tetrakis-adducts of C70, featuring two covalently attached crown ethers, form stable 1:1 and 1:2 host-guest complexes. Comparative studies showed that the conformation of the DB18C6 ionophore imposed by the macrocyclic bridging to the fullerene is not particularly favorable for strong assocn. Electrochem. studies demonstrated that cation complexation at the crown ether site causes significant anodic shifts of the first redn. potential of the appended fullerene. In case of the C70 mono-crown ether conjugates featuring a five o'clock functionalization pattern, addn. of 1 equiv. of KPF6 caused an anodic shift of the first redn. wave in the cyclic voltammogram (CV) by 70 to 80 mV, which is the result of the electrostatic effect of the K+ ion bound closely to the fullerene core. Addn.There are some commonly used reagents with their cas registry numbers 36239-09-5 and 87976-35-0 in this article. of 2 equiv. of K+ ions to C70 bis-crown ether conjugates resulted in the observation of only one redox couple, whose potential is anodically shifted by 170 mV with respect to the corresponding wave in the absence of the salt. Attempts to prep. even more highly functionalized derivs. resulted in the formation of novel pentakis- and hexakis-adducts and a single heptakis-adduct, which were characterized by 1H- and 13C-NMR spectroscopy, as well as matrix-assisted laser-desorption-ionization mass spectrometry (MALDI-TOF-MS). Based on predictions from d.-functional-theory (DFT) calcns., structures are proposed for the tris-, tetrakis-, and pentakis-adducts. .
