Melting Point and Molecular Symmetry
Autor: R. F. C. Brown, R. J. C. Brown
Publikováno v: Journal of Chemical Education. 77:724
In 1882 Thomas Carnelley observed that high molecular symmetry is associated with high melting point. The application of the rule to a number of different molecular crystals is discussed. The rule applies to different categories of crystal for differ

Iron deficiency and the growth of pea roots
Autor: R. F. C. Brown, J. V. Possingham
Publikováno v: Proceedings of the Royal Society of London. Series B - Biological Sciences. 147:145-166
Pea roots have been cultured in sterile media in the presence and in the absence of added iron, and the effects of deficiency have been studied in three series of experiments. In the first, roots grown in deficient and full nutrient media were taken

Demonstration of lack of inversion of the migrating allyl group in photochemical rearrangement of a hexa-1,5-diene derivative
Autor: R.C. Cookson, J. Hudec, R. F. C. Brown
Publikováno v: Tetrahedron. 24:3955-3964
UV irradiation of trans-2-(3′-deuterioallyl)cyclohexylidenemalononitrile (XIa) induces rearrangement to allyl-1-cyclohexenylmalononitrile, in which the deuterium is still entirely at the 3-position of the allyl group but has lost its geometrical co

The stimulant involved in the germination of Striga hermonthica
Autor: Alexander Todd, A. W. Johnson, Eric Robinson, R. F. C. Brown
Publikováno v: Proceedings of the Royal Society of London. Series B - Biological Sciences. 136:1-12
The seeds of Striga hermonthica will only germinate readily when they have been exposed to a chemical stimulant released from a potential host root, and the purpose of the investigation has been the examination of the chemical nature of the stimulant

The formation of a rearranged product on dehydration of a bicyclic nitrone-hydroxylamine
Autor: Lord Todd, V.M. Clark, R. F. C. Brown
Publikováno v: Tetrahedron. 22:15-26
Dehydration of the nitrone-hydroxylamine (II) with toluene- p -sulphonyl chloride and triethylamine gives the rearranged product. 2,3,4,5-tetrahydro 5,5-dimethyl 3-oxo-2-(4′,5′,5′-trimethylpyrrolidin-2′ ylidene) pyridine (III). The benzoate o

The effects of D-xyloketose and certain root exudates in extension growth
Autor: Eric Robinson, A. W. Johnson, R. F. C. Brown
Publikováno v: Proceedings of the Royal Society of London. Series B - Biological Sciences. 136:577-591
This investigation has been designed, to examine the possibility that the substance which is exuded from the roots of Sorghum seedlings, and which stimulates the germination of the seeds of Striga hermonthica , may promote extension growth in the roo
