Mn-Catalyzed oxidative amination of benzylic C(sp3)–H bonds with nitriles is disclosed, which enables the synthesis of a broad range of secondary amides in moderate to excellent yields under mild conditions. The interaction between Mn(III) and DDQ facilitates the oxidation and makes it highlyefficient and selective.

Bis‐sulfamyl imines are shown to be potentially ideal substrates for rhodium‐catalysed asymmetricadditions of arylboron nucleophiles as they show: (i) near perfect enantioselectivities (11 examples, 98–99+% ee), (ii) good to excellent diastereoselectivities (10–32:1 rac:meso), and (iii) high functional group tolerance in removal of the low molecular weight protecting group via mild heating in aqueous

The paper reviews industrial relations developments in Britain during 1999 by assessing how New Labour’s policy commitment to encouraging ‘partnership’ is developing in practice. After a discussion of the Employment Relations Act, it considers the wider influence of European legislation. It then describes how partnership approaches have been developing in trade union policy and industrial practice. This leads to an analysis of the operation of two explicit ‘social partnership’ institutions, ACAS and the Low Pay Commission. The paper ends with a consideration of the developing arguments at the ILO and WTO over international labour standards.
