Pheny lamine

Diimines 3 of 2,2,4,4-tetramethylcyclobutane-l,3-dione were formed by the addition of an excess of primary amines in the presence of titanium(IV) chloride.293- 294 When one equivalent of the amine was used, the mono-imine 2 was isolated. If steric hindrance is a limiting factor, this method is preferred.294 However, an ordinary water separation trap can also be used, omitting the titanium(IV) chloride.295-296 In the latter case, the use of chiral amines such as ( + )-dehydroabietylamine, (+)-ris-2,2-dimethyl-6-phenyl-l,3-dioxan-5-arnine or (-)-a-pheny-lamine, can be used to resolve a racemic mixture of 3,7,7-trimethylbicyclo[3.2.0]hept-2-en-6-one via the corresponding imines.296... 

Methylamine is a stronger base than phenylamine, because in pheny-lamine the delocalised electon cloud of the benzene ring extends to overlap with the lone pair of electrons of the N. This makes it harder for the lone pair to donate to the a proton. So phenylamine is a weaker base (Figure 7.3.11).

Aromatic amines are initially metabolized by aromatic and A-hydroxylation (oxidation reactions) and A-acetylation. Following aromatic ring hydroxylation, the ring structure may be further conjugated with glucuronic acid or sulfate (Parkinson 1996). N-hydroxylation results in the potential methemoglobin-generating metabolite, pheny Ihydroxy lamine. 

The reinforcing fabrics used were aramid (Kevlar DuPont) and poly(p-pheny-lene-2,6-benzobisoxazole) (PBO) (Zylon Toyobo). The fabrics were first treated with a 1.5% solution of HB PAMAM (AD-102), dried, then interleaved with an epoxy film structural adhesive (epoxy stage B on polyester net), and compression-molded for 90 min at 120 °C. For the aramid-based composite, FM-73 (Cy-tec) was used as the matrix. For the PBO-based composite, AF-191 (3M) was used as the matrix. The laminates were cut into strips and tested for interlaminar shear strength (ASTM D-2344) using a three-point bending instrament.
