The IR spectrum of each 1,3-dioxepin-MA copolymer, with anhydride bands at 1775 and 1855 cm-1, acetal or ketal three band pattern for C-O-C stretching located around 1100 cm-1 and the acetal bending band at 925 cm-1 was supportive of materials with MA and 1,3-dioxepin residues. In some cases acid functionality was indicated by a weak carbonyl band at 1725 cm-1, appearing as a distinct shoulder of the 1775 band. The free acid hydroxyl was less evident in the 2400-3600 cm-1 region. The IR spectrum band shapes in the CH stretching regions could also be correlated with isopropyl, methyl, phenyl and methylene substituents at the 2-position of the various 1,3-dioxepin residues.

Methyl m-tolyl (8), ethyl m-tolyl, methyl n-butyl and methyl n-propyl sulfoxides were obtained in 100% e.e. This method was less successful when applied to methyl phenyl sulfoxide (5% e.e.) or to methyl isobutyl and methyl ethyl sulfoxides (25% e.e.). No complexes were formed between methyl o-tolyl, methyl p-tolyl, methyl 2-butyl and methyl isopropyl sulfoxides so these compounds could not be resolved using 7. A crystal structure of the 1 1 complex formed between 7 and 8 revealed that the partners were linked by OH—OS hydrogen bonds in endless zig-zag chains23. More recently, 2-chloroethyl m-tolyl sulfoxide (9) has been resolved using 724. 

In the course of this study, the authors determined /Lvalues for dibenzyl, methyl phenyl, methyl p-nitrophenyl, di-p-tolyl, di-isopropyl and tetramethylene sulphoxides and for diethyl, dipropyl and dibutyl sulphites. The /Lscales are applied to the various reactions or the spectral measurements. The /Lscales have been divided into either family-dependent (FD) types, which means two or more compounds can share the same /Lscale, family-independent (FI) types. Consequently, a variety of /Lscales are now available for various families of the bases, including 29 aldehydes and ketones, 17 carboxylic amides and ureas, 14 carboxylic acids esters, 4 acyl halides, 5 nitriles, 10 ethers, 16 phosphine oxides, 12 sulphinyl compounds, 15 pyridines and pyrimidines, 16 sp3 hybridized amines and 10 alcohols. The enthalpies of formation of the hydrogen bond of 4-fluorophenol with both sulphoxides and phosphine oxides and related derivatives fit the empirical equation 18, where the standard deviation is y = 0.983. Several averaged scales are shown in Table 1588.

Optically active O-isopropyl (5)-( — )-methylphosphinothioate (136) has been prepared for the first time by reaction of isopropy (/ )-(- )-methyl-phosphinate (137) with P4S10. The retention of configuration at phosphorus during this conversion was established by the formation of the two enantiomers, (138) and (139), of O-isopropyl 5-phenyl methylphosphonodithioate by separate routes of known stereochemistry. 

Snyder et al. [253] compared supercritical fluid chromatography with classical sonication procedures and Soxhlet extraction for the determination of selected insecticides in soils and sediments. In this procedure the sample was extracted with carbon dioxide modified with 3% methanol at 350atm and 50°C. An excess of 85% recovery of organochlorine and organophosphorus insecticides was achieved. These included Dichlorvos, Diazinon, (diethyl-2-isopropyl-6-methyl 4-pyrimidinyl phosphorothioate), Ronnel (i.e. Fenchlorphos-0,0 dimethyl-0-2,4,5-trichlorophenyl phosphorothioate), Parathion ethyl, Methiadathion, Tetrachlorovinphos (trans-2-chloro-l-(2,4,5 trichlorophenyl) vinylchlorophenyl-O-methyl phenyl phosphoroamidothioate), Endrin, Endrin aldehyde, pp DDT, Mirex and decachlorobiphenyl.

The reaction of 3,4-benzo-l,2-disilacyclobutene (22) with Cgo yields the corresponding disilacyclohexane derivative (23)20. Irradiation of a solution of disilacyclobutene 22 and Cgo in toluene with a low-pressure mercury lamp (254 nm) afforded the brown adduct 23 in 14% yield (based on unreacted Cgo) (equation 8). The FAB mass spectrum of 23 exhibits one peak at m/z 1024-1027 (C7sH32Si2, M+, molecular cluster ion), as well as one for Cgo at m/z 720-723. The -NMR spectrum of 23 showed a symmetrical spectrum with two diastereotopic isopropyl methyl protons, one isopropyl methine proton and a AA BB pattern assigned to phenyl protons. The 13C-NMR spectrum of 23 shows 17 signals for the Cgo skeleton, of which four correspond to two carbon atoms each and 13 correspond to four carbon atoms each one signal appears at 63.93 ppm and the remainder between 130 and 160 ppm (Scheme 7, Figure 10). This pattern is consistent...
