In the examples (1) styrene was polymerized in an aq. mixture of polyvinyl alcohol, n-pentane, m-tetrabromobutane, dibenzoyl peroxide and 4,4 - dimethyl - N - (1 - yl - 1 - tert.- butylperoxi - ethyl) - azetidinone; and (2) styrene was polymerized as in (1) but with ...
Acylation of alcohol The high catalytic activity of DMAP and PPY can be used for acylating sterically hindered secondary or tertiary alcohols with carboxylic anhydrides or acyl halides when the pyridine method fails. In most cases, it is necessary to use only 0.05-0.2 mol of catalyst per mol ...

The presence of the labile N–O bond, which can be easily cleaved under mild reducing conditions, accounts for the common use of isoxazolidines as masked 1,3-amino alcohols. The reductive ring opening of an isoxazolidine is mostly performed by hydrogenation in the presence of catalysts ...
