Unsaturated, carbonyl and aromatic products were obtained by reacting 1-butanol or a 1-butanol:methanol mixture with a copper mixed metal oxide catalyst in a fixed bed reactor. The selectivities observed, mostly for the unsaturated and carbonyl products, can represent a new alternative and greener pathway for the production of fine-chemicals and organic building blocks.
METHOD FOR THE PRODUCTION OF OLEFINS COMPRISING 8 TO 12 CARBON ATOMS

Page/Page column 32-33, (2010/02/13)
The invention relates to the production of olefins or olefin mixtures comprising 8 to 12 carbon atoms by means of a four-stage synthesis from one or several olefins containing 4 to 6 carbon atoms. Said four-stage synthesis encompasses the steps of hydroformylation to obtain aldehyde, hydrogenation to obtain alcohol, dehydration to obtain 1-olefin, and metathesis. The obtained C8 to C12 olefins can be used for the production of plasticizer alcohols, for example, particularly isononanol.
HOMOALLYLIC SUBSTITUTION REACTIONS OF LITHIUM DIALKYL CUPRATES WITH CYCLOPROPYLCARBINYL HALIDES: MECHANISTIC CONSIDERATIONS

Highly reactive lithium dialkyl cuprates and 1-bromo-1-cyclopropylalkanes, 4, react to give good yields of the homoallylic substitution product, 6.Less reactive organocuprates react with 4 to give mixtures of 6 and the direct substitution product 7.These results are consistent with a copper(I) radical intermediate which undergoes facile rearrangement prior to reductive coupling.
Photochemistry of Thietane Excited to Its Second Excited Electronic Singlet State

Thietane, excited to its S2 state, undergoes fragmentation to ethylene and thioformaldehyde by one channel and a competing reaction, unique to the S2 state, is decomposition to cyclopropane and sulfur atoms.Previous work on the S2 state of thietane has been extended to include a more detailed examination of the spectra and energy partitioning in the cyclopropane formimg reaction; and, by photolizing cis- and trans-3-ethyl-2-propylthietane, we have followed the stereochemical course of both reaction channels.The products of both reactions largely retain the stereochemistry of the reactant.Energy partitioning indicates that S(3P) is the atomic fragment when cyclopropane is produced.A mechanism which accomodates the experimental results assumes that, once excited to its 1B2 electronic state, intersystem crossing to the 3B2 state competes with C-S bond rupture that forms the 1,4-diradical intermediate which yields the ring cleavage products.The 3B2 state decomposes to cyclopropane and S(3P) by a mechanism that likely involves a singlet trimethylene diradical as an intermediate.
