A pyrolysis of cis-1-trimethylsiloxy-1-cyclopropyl-3-cyclononene : the thermal isomerization of 2-phenyl-1-trimethylsiloxy-1-vinylcyclononane

Creator:: Choi, Young Bok
Abstract:: Part 1 The pyrolysis of cis-1-trimethylsiloxy-1-cyclopr opyl-3-cyclononene in the temperature range 285-350° is described. Instead of siloxy-Cope rearrangement, undesired desiloxylation took place. Part 2 Gas-phase pyrolytic rearrangement of 2-phenyl-1-trimethylsiloxy-1-vinylcyclononane was investigated in a static system in the temperature range 213-330°. It was discovered that three major products resulted: cis- and...

Oxy-Cope, and Siloxy-Cope rearrangement of cis-1-vinylcyclooct-3-en-1-ol

Creator:: Chin, Alice Wai-lee
Abstract:: Both oxy-Cope and siloxy-Cope rearrangements involve (1, 3) and (3, 3) sigrnatropic shifts. Both the concerted mechanism, and the stepwise mechanism via a diradical intermediate are possible. In a cyclic system such as cis-l-vinylcyclooct-3-en-l-ol, the thermal rearrangement takes place preferably through a diradical intermediate. At high temperature, the reaction also...

The siloxy-cope rearrangement of 1,2-divinyl-1-trimethyl-siloxycyclohexane and related systems. The acid-catalyzed rearrangement of bicyclo [5.1.0] octyl-8-methanol

Creator:: Walton, Edward Samuel
Abstract:: Part I The pyrolysis of cis- and trans- 1, 2-divinyl-1- trimethylsiloxy - cyclohexane, II- and III-TMS, under the same conditions as the pyrolysis of cis-l-vinyl -1-trimethylsiloxycyclooct-3-ene, I-TMS, confirms that a sequence of concerted reactions for the rearrangement of II- and III-TMS to trans-l-trimethylsiloxycyclodec-3-ene, IV-TMS, is a viable pathway in the...

The photodecomposition of t-butyl bicyclo [7.1.0] decane-2-percarboxylate

Creator:: McRitchie, Donna Louise
Abstract:: This paper describes the synthesis of t-butyl bicyclo[7.1.0] decane-2-percarboxylate and its photolytic decomposition. The title compound was found to undergo simple homolytic cleavage when exposed to light of 2537 A; producing the cyclodecyl radical, carbon dioxide, and t-butoxy radical. The largest percentage of products arose from an intimate radical pair...

Oxymercuration of cyclodeca-1,2,5,8-tetraene

Creator:: Hong, Pak-Kong
Abstract:: The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts in solvents of varying nucleophilicity are described. Instead of forming the usual oxymercuration products reported for reactions of olefins and allenes with mercuric salts, the major products obtained in the present cases result from the initial electrophilic addition of the...

Siloxy-cope rearrangements of the trans-l-vinylcyclotridec-3-en-l-ol system

Creator:: Bolesta, Richard Edward
Abstract:: The thermolysis of trans-1 -trimethylsiloxy- 1-vinylcyclotridec- 3-ene (VI-OTMS) led to the formation of two major products: 4-vinylcyclotridecanone (VII) and cyclopentadec-5-en-l-one (VIII) after hydrolysis. Ketone VII is produced by a concerted [3, 3] sigmatropic shift, while ketone VIII is formed by a [1, 3] sigmatropic shift with a concerted or diradical...

Catalytic rearrangement of cyclodeca-1,2,5-triene and oxymercuration of bicyclo-[7.1.0]-deca-2,3-diene

Creator:: Boop, Janice Lee
Abstract:: The reaction of cyclodeca-1,215triene with mercuric salts gave only rearranged hydrocarbon, tricyclo[4.4.0.0²'⁴]deca-5ene in acetic acid. Other catalysts [Rh(CO)₂C1]₂ and AgC10₄ gave the same rearranged hydrocarbon. The isomerization is proposed to proceed through a "metalcomplexed" carbenoid intermediate. The reaction of bicyclo[7.1.0 ]deca-213diene gave oxymercurated products.

Thermal [pi]-route rearrangement of 4-cycloheptane-1-methyl acetate

Creator:: Schick, Lawrence Edward
Abstract:: Pyrolysis of 4-cycloheptene-l-methyl acetate under flow conditions at 285° gives only rearranged bicyclic acetates and hydrocarbons rather than the anticipated simple elimination product methylenecyclohept- 4-ene. These rearranged acetates have the same structures and are formed in virtually the same relative percentages as those observed in the "π- route" solvolysis of...
