Some obscurities. Each of the reactions mentioned has been identified in at least one system, but there are very many obscurities to be cleared up. For example, transfer by methyl vinyl ether, phenyl vinyl ether, vinyl acetate and some of the corresponding polymers in the polymerization of styrene by stannic chloride has been studied, but the mechanism is not at all clear [124].

For conversion of functionalized diorganozincs into tertiary amines, aromatic compounds which contain a directed metallation group, such as Af,Af-dialkylbenzamides, methoxymethyl phenyl ether, phenyl oxazolines and phenyl Af,Af-dialkylcarbamates, were ortho-lithiated, transmetallated and then aminated with 2a in good yields, but with a slower reaction rate (Scheme 19).

Phenyl Ethers Phenyl ethers (one of the groups bonded to oxygen is a benzene ring) react with HBr or HI to give alkyl halides and phenols. Phenols do not react further to give halides because the s/r-hybridized carbon atom of the phenol cannot undergo the Sn2 (or SN1) reaction needed for conversion to the halide.

In the present context, the term electron rich alkenes refers primarily to enol ethers, enol sulfides, and A-vinylamides or A-vinylamines. Such alkenes are typically much more readily ionizable than are simple alkenes. The conversion of these substrates to the corresponding (highly electron deficient) cation radicals represents a sharp Umpolung. The Diels-Alder additions of tra j -anethole, phenyl vinyl ether, phenyl vinyl sulfide, 1,3-dioxole, and A-methylindole to 1,3-cyclohexadiene have been reported (Scheme 22) [49, 52]. 

If the two groups arc identical, the ether is said to be symmetrical (c.g., ethyl ether, phenyl ether), if different, unsymmetrical (e.g., methyl tert-butyl ether, anisole).

Mesogenic PEIs are obtained when m-aminophenol is replaced by p-ami-nophenol. A mesophase is correctly predicted in all four polymers of series 11 in Table 23. Each of the four different aromatic acids from ether diphenyl (MI score=l) to ether phenyl diphenyl (MI score=4) gives rise to a mesophase, unlike the series with pyromellitic. The Mesogenic Index approach confirms that BPTA is a much stronger mesogen than pyromellitic diimide. In fact, it predicts that if the fourth co-monomer in series 11 was an aliphatic spacer, a mesophase would still be obtained.
