Dibenzyl-methyl

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. [Pg.559]

Man erhalt auf diese Weise z.B. aus Benzyl-methyl-amin Dibenzyl-methyl-amm (24%) und aus Butyl-methyl-amin Dibutyl-methyl-amin ( 60%). In anderen Fallen sind die Ausbeuten z.T. wesentlich schlechter. [Pg.1214]

When using mixed phosphites, some useful regioselectivity is possible in the dealkylation step, thus benzyl is lost in preference to alkyl groups, for example, from dibenzyl methyl phosphite,19 and silyl in preference to alkyl groups (see below). [Pg.183]
