Enantioselective reactions of some optically active phosphines

Jay, G. F. January 1987 (has links)
The enantioselective chlorination of alcohols by the menthyldipheny1-phosphine/carbon tetrachloride reagent previously reported in the literature was investigated and quantified. Further examples were found. A new enantioselective reaction of menthyldipheny1phosphine/carbon tetrachloride was discovered. This was the synthesis of aziridines by ring closure of ? amino alcohols. Other optically active phosphines in conjunction with carbon tetrachloride were found to react in a similar manner to menthy1dipheny1phosphine/carbon tetrachloride with a variety of ? amino alcohols. Menthy1dipheny1phosphine was found to react enantioselectively with a ? amino alcohol in the presence of chlorine.

A very high resolution X- and Ku-band field study of a barley crop in support of the SWINTOL Project

Bermejo, J P 10 August 2016 (has links)
SAR Wave INteraction for Natural Targets Over Land (SWINTOL) is a project funded by the European Space Agency. The study’s goal is to better understand the interaction of high frequency radar (> X-band) with vegetation and soils, in order to drive the development of a high-frequency electromagnetic model to simulate SAR imagery at high resolution (< 1 m). Existing models work well at C and X band frequencies, but do not work properly at higher frequencies. Cranfield University’s role in this project was to provide the field data necessary for model validation and development. Radar imagery was taken of a barley crop over an entire growing season. The portable outdoor GB-SAR system used the tomographic profiling (TP) technique to capture polarimetric imagery of the crop. TP is a scheme that provides detailed maps of the vertical backscatter pattern through a crop canopy, along a narrow transect directly beneath the radar platform. Fully-polarimetric imagery was obtained across overlapping 6.5 GHz bandwidths over the X- and Ku-band frequency range 8-20 GHz. This gave the opportunity to see the detailed scattering behaviour within the crop at the plant component level, from emergence of the crop through to harvesting. In combination with the imagery, full bio-geophysical characterisation of the crop and soil was made on each measurement date. Surface roughness characterisation of the soil was captured using a 3D optical stereoscopic system. This work details the measurements made, and provides a comparative assessment of the results in terms of understanding the backscatter in relation to biophysical and radar parameters.
