A synthesis of the title phosphinamine (PHENAP) is described, following previously established methodology.Resolution via the C,N-palladocycle derived from (R)-N,N-dimethyl-α-methyl-1-naphthylamine led to two crystallographically defined complexes with the (R,S)-form posessing a chelated ligand and the (R,R)-form open with only the phosphine coordinated.Palladium allyl complexes of the ligand were strikingly different from those of the corresponding isoquinoline ligand QUINAP, and the differences could be rationalised by recourse to molecular models, with the additional fused arene ring of PHENAP playing a critical part in defining the coordination sphere through its steric pressure.A brief appraisal of Pd-catalysed allylic alkylation reactions was performed with the new ligand.

Described is an asymmetric synthesis of cyclic and acyclic allylic S-aryl. and S-alkyl sulfones through a highly selective palladium(0)-catalyzed 1,3-rearrangement of racemic allylic sulfinates. Treatment of racemic cyclic and acyclic allylic S-tolyl- and

The mechanism of rearrangement of a number of allylic sulphinate esters to the corresponding allylic sulphones on heating in formamide has been investigated as a function of substrate structure.Simple systems such as crotyl and α-methylallyl-sulphinate ap
