A-Allylnaphthalene

Alternating copolymers of a-allylnaphthalene with MA have received only brief study.Heating equimolar amounts of the two monomers at 160-180°C, in the presence of 2-4 wt. % tert-buty peroxide, gives a 77% yield of the 1 1 copolymer.

The third group ofpolychromophoric compounds to be discussed are homopolymers in which the pendant rings are separated from the backbone by one or more atoms. The polymers of allyl arenes, which lack only the n = 3 ring spacing of aryl vinyl polymers, have been studied very little. The fluorescence spectrum of poly(l-allyl-naphthalene) in dilute dichloromethane solution has been reported 28). Like 1-ethyl-naphthalene, the maximum intensity was seen at 337 nm, but a weak, broad shoulder was also recorded for the polymer at 410 nm. The fluorescence ratio Iu/IM for poly(l-allylnaphthalene) was only 1/100 th the value for P1VN 28). The excimeric nature of the 410 nm emission in the allyl-based polymer has not been confirmed, since neither the lifetime nor the excitation spectrum of this fluorescence band are known. 

Sol 4. (a) Allyl ether of 2-naphthol (I) on heating undergoes Claisen rearrangement to give l-aIlylnaphthalen-2-ol (II) and 3-allylnaphthalen-2-ol (HI). Reaction favors the formation of II as the aromaticity in the intermediate enone is lost only in one ring. However, in the formation of III aromaticity in the intermediate enone is lost in both the rings.
