Emergência de Merremia cissoides, Mucuna aterrima e Neonotonia wightii sob diferentes profundidades de semeadura e quantidades de palha de cana-de-açúcar Emergence of Merremia cissoides, Mucuna aterrima, and Neonotonia wightii under different sowing depths and amounts of sugarcane straw

open access: yesPlanta Daninha, 2011
Objetivou-se neste trabalho avaliar a influência da profundidade de semeadura e da condição de cobertura do solo na emergência de Merremia cissoides, Mucuna aterrima e Neonotonia wightii. Foram realizados dois experimentos, para cada espécie. No primeiro, os tratamentos foram organizados em esquema fatorial 4 x 2, considerando-se quatro condições de ...

Is gauche attraction between the fluoro atom and the incoming nucleophile really the determining factor in cissoid stereochemistry?

Journal of Fluorine Chemistry, 1992
Abstract Recently we described the unexpected concomitant formation of the ‘antigauche’ trans isomer during the synthesis of 5-fluoro-6-alkoxyuracils ( J. {Fluorine Chem., 54} (1991) 190). With respect to their conformation, in both the cis and the trans compounds, the anomeric effect (substituent at C 6 axial to N 1 ) appeared to be the ...
