Zur Reaktionsweise metallorganischer Verbindungen. V. Mitteilung. Die Arylphenol‐Umlagerung gemischter Diaryläther

Abstract: tfber Chinovasllure. IX. 26 Nach dieaer Zeit wurde in eine Dampfschale geapiilt und im Exsikkator zur Trockene gestellt. Der Rtickstand wurde dreimal a m 2-3 n-Natronlauge umkristallisiert, wobei daa zentrifugierte gristallisat jedeamal zunllchst in Wasser gelUst war. Das Natrinmealz erscheint beim Abktihlen in schUnen Prismen. Sodann wird die vorgereinigte L6sung mit Barytwasser versetzt und die derberen Kristalle des Bariamsalzes werden erneut umkristallisiert. Die freie S&ure wurde in Ather aufgenommen and … Show more

“…The reaction of phenyl-and alkylsodium compounds with diaryl ethers leads to an interesting rearrangement of the diaryl ethers to o-arylphenols (33,34,35,36). Thus, diphenyl ether with phenylsodium gives a 45 per cent yield of o-phenylphenol (XXVIII), a 9 per cent yield of 2-phenoxybiphenyl (XXIX), Direct ether fission by the phenylsodium seldom occurs with ethers of this type; instead, the first step is considered to be metalation in the position ortho to the oxygen atom.…”

“…Instead the predominant reaction was cleavage of the ether linkage to give phenol. Likewise, diphenyl ether was cleaved by triphenylmethylsodium to give tetraphenylmethane (35). R. Paul (76,77) has studied the metalation of vinyl ethers with organosodium reagents.…”

“…Diphenyl disulfide is reported to be formed by long treatment of diphenyl sulfide with phenylsodium or benzylsodium (163); the disulfide is also obtained by boiling the sulfide with sulfur (246). Diphenyl ether reacts differently with phenylsodium, giving cleavage of the ether linkage, and some arylation (265). A series of diaryl sulfides containing a phenolic hydroxyl group either ortho or para to the sulfur has been found to undergo displacement of the sulfur by typical electrophilic reagents, such as chlorine, bromine, nitric acid, sulfuryl chloride, and benzenediazonium chloride (315,316); the following reaction is representative.…”

“…One of the products obtained from diphenyl ether is 2'-hydroxym-terphenyl (10 per cent yield) (97). Other hydroxyterphenyls are formed from 3-and 4-biphenylyl phenyl ether (98). When p-cresol is oxidized with ferric chloride, a ring-coupling reaction occurs, 2,2'-dihydroxy-5, S'-dimethylbiphenyl (10 per cent yield) and 2,2', 2"-trihydroxy-5,5', 5"-trimethyl-m-terphenyl (6 per cent yield) being produced (31).…”
