  Intramolecular Reactivity of Arylcarbenes: Derivatives of o-Tolylcarbene

  摘要：

  Various CH(2)X groups have been attached to the ortho position of phenylcarbene. If 2'- or 3'-C-H bonds are present, as in 23 (X = Me), 71 (X = CMe(3)), and 58 (X = SiMe(3)), C-H insertion leading to five- or six-membered rings predominates in the gas phase and competes with intermolecular reactions in solution. The formation of benzocyclobutenes via insertion into 1'-C-H bonds is a very minor reaction path of 23 and 71. In contrast, 58 produces substantial amounts of the benzocyclobutene 59 by way of C-Si insertion, particularly in the gas phase. Insertion into the Si-Me bonds of 58 also occurs while the C-F bonds of 37 (X = CF3) and 50 (X = Fl are inert. In the gas phase, 37 and 50 give mainly benzocyclobutenes whereas intermolecular reactions prevail in solution. The effects of sensitization and of solvent polarity suggest that benzocyclobutenes arise from singlet arylcarbenes. The amount of carbene-carbene rearrangement decreases in the order 7 (X = H) > 37 (X = CF3) > 23 (X = Me); no rearrangement was observed with 50 (X = Fl, 58 (X = SiMe(3)), and 71 (X = CMe(3)).

  triplet states contribute to the intramolecular CH insertion reactions of 2- (alkoxymethyl)phenylcarbenes, leading to dihydro-1 H-2-benzopyrans. Competitively, oxygen ylides are generated which eventually give rise to benzocyclobutenes and dihydroisobenzofurans. The radical pair mechanism of the Stevens rearrangement is confirmed by variation of the alkyl groups and by means of chiral substrates.

  Aromatic compounds having an alkyl group with at least 3 carbon atoms are produced in a process comprising at least one of the following steps: (1) a step of contacting a starting material that contains an aromatic compound having a branched alkyl group with at least 3 carbon atoms, with a zeolite-containing catalyst in a liquid phase in the presence of hydrogen therein, thereby changing the position of the carbon atoms of the alkyl group bonding to the aromatic ring of the compound; (2) a step of contacting a starting material that contains an aromatic compound having a branched alkyl group with at least 3 carbon atoms, with a catalyst containing zeolite and containing rhenium and/or silver, in a liquid phase, thereby changing the position of the carbon atoms of the alkyl group bonding to the aromatic ring of the compound; (3) a step of contacting a halogenated aromatic compound having an alkyl group with at least 3 carbon atoms, with an acid-type catalyst, thereby isomerizing the compound; and (4) a step of treating a mixture of isomers of an aromatic compound having an alkyl group with at least 3 carbon atoms, with a zeolite adsorbent that contains at least one exchangable cation selected from alkali metals, alkaline earth metals, lead, thallium and silver, thereby separating a specific isomer from the isomer mixture through adsorption.
