Trifluoroacetimidoyl metal complexes are useful intermediates for the selective synthesis of organofluorine compounds. Herein, we report preparations, structures, and reactions of fluorinated imidoyl palladium complexes. Oxidative addition of trifluoroacetimidoyl halides to Pd(PPh3)4 afforded quantitatively the imidoyl palladium(II) complexes with phosphine ligands. The reaction of trifluoroacetimidoyl iodides with Pd 2(dba)3 provided the phosphine-free imidoyl palladium complex in high yields. The X-ray crystal structure analysis of the phosphine-free complex [Pd(mu-I){mu-C(CF3)=N(PMP)}]4 revealed a cyclic tetranuclear structure containing the imidoyl and iodo bridges. The generation of aminotrifluoromethylcarbene equivalents by protonation or electrophilic alkylation of imidoyl palladium(II) complexes is discussed.

The first asymmetric synthesis of important alpha,alpha-disubstituted N-alkyl allyl amine scaffolds through allylic substitution is reported. This approach is based on palladium catalysis and features ample scope with respect to both the allylic precursor and amine reagent, and high asymmetric induction with enantiomeric ratios (e.r.) up to 98.5:1.5. The use of less-reactive anilines is also feasible, providing enantioenriched alpha,alpha-disubstituted N-aryl allylic amines.

Reactions of Pd(PPh3)4 with P(=E)(N iPr2)(naph) (6, E = S; 7, E = O) (naph = 1,8-naphthylene) having a strained four-membered P(V)-phosphacycle gave dimeric complexes [Pd{kappa2P,C-mu2-PEP(=E)(NiPr 2)(naph)}(PPh3)]2 (9, E = S; 10, E = O), in which a Pd metal has been inserted into a P-C bond of the phosphacycle to form a phosphapalladacycle having a P(V) donor, and the two phosphapalladacycle units have been mutually bridged with E=P groups, as confirmed by X-ray structure analysis for thermodynamically more stable racemic isomers 9a and 10a. The meso-to-racemic isomerization observed for the simultaneously formed meso isomer 9b, and probably also for the corresponding meso isomer 10b, indicated partial dissociation of 9 and 10 taking place to their monomer units in solution, which were actually trapped as [Pd{kappa2P,C-P(=E)(NiPr 2)(naph)}(dppe)] by treatment with bidentate dppe (dppe = 1,2-bis(diphenylphosphino)ethane). On the other hand, a similar treatment of 9a with monodentate PMe3 and PEt2Ph resulted in a trivial substitution of both PPh3 ligands to give dimeric PMe3 and PEt2Ph analogues of 9a, respectively. 10a was found to react with O2 to form an unprecedented oxidation product, [Pd{kappa 2P,O-mu2-PO-PO(=O)(NiPr2)(naph)}(PPh 3)]2, 17, in which an oxygen atom has been inserted into each P(V)-Pd bond. 9a and 10a exhibited moderate catalytic activities for a Heck reaction between PhI and styrene. The mercury test indicated that metallic Pd nanoparticles released from 9a and 10a would be practical catalysts.
