Abstract

Aryl or allyl ethers of some heterocyclic systems can be readily hydrogenolysed or cross- coupled catalytically with transition metals to give arenes, alkenes or alkanes. Unexpectedly for transition metals, the corresponding alkyl and, particularly, benzyl ethers are totally inert. An X-ray structure determination on 3-benzyloxy-1, 2-benzisothiazole 1, 1-dioxide 1 has shown that there is no inherent structural reason for this major difference, apart from the ...
