Stereodynamics of N-allyl-N-methyl-2-aminopropane. 1H and 13C{1H} DNMR studies. Molecular mechanics calculations

N-Allyl-N-methyl-2-aminopropane (AMAP) is a relatively simple tertiary amine that has a chiral center at the pyramidal nitrogen. The 1H and 13C{1H} dynamic nuclear magnetic resonance (NMR) spectra of AMAP show a higher temperature decoalescence due to slowing inversion-rotation at nitrogen and a more complex decoalescence at lower temperatures due to slowing isolated rotation about carbon-nitrogen bonds. A well-defined 1H NMR spectrum at 100 K is simulated accurately by invoking the presence of five equilibrium conformations including two conformers that interconvert rapidly at 100 K.

A palladium/norbornene cooperative catalyzed selective C-H bond amination of aryl iodides was explored, providing an efficient tool for constructing benzocyclic molecules. When ortho-substituted iodobenzene was involved, the C-H bond amination and following Heck cyclization efficiently delivered a 3-methyl-indole scaffold. On the other hand, we realized the controllable synthesis of monoaminated benzo-cyclobutanyl scaffold. The possible coordination of an installed terminal alkenyl group with palladium and steric hindrance were proposed to be responsible for the monoamination selectivity.

The N,N′,N-triphenyl-substituted derivative of tris(2-aminoethyl)phosphine (Ph3-phospha-tren, P(CH2CH2NHR)3, R = Ph) and four derivatives of the related tris(3-aminopropyl)phosphine (phospha-trpn, P(CH2CH2CH2NHR)3, R = iPr, tBu, SitBuMe2, Ph) have been synthesized in addition to the parent phospha-trpn. Out of these ligand systems, only the N,N′,N-triphenyl-substituted phospha-trpn derivative P(CH2CH2CH2NHPh)3 was found to be suitable for coordination to group 4 metals. For titanium, zirconium, and hafnium, the C3-symmetric endo-P-configured dimethylamido complexes Ph[PN3]M(NMe2) of the former ligand have been prepared and converted into the corresponding triflates Ph[PN3]M(OTf). Starting from these triflates, the benzyl complexes Ph[PN3]M(Bn) (M = Ti, Zr, Hf) have been obtained via reaction with Bn2Mg(THF)2. In case of titanium, the benzyl species Ph[PN3]Ti(Bn) is prone to thermal elimination of toluene, which results in the formation of a cyclometalated species. These findings are discussed in context with the very few group 4 trisamidophosphine complexes that have been reported earlier.
