Quasi-template Effect: a Tool for Controlling Stereochemistry in Acyclic Systems. Attempted Stereoselective Synthesis of α,α'-Dimethoxystilbene

Alkylation with methyl tosylate of stilbenediol dianion, prepared in the reaction of benzoin with a series of alkali-metal hydroxides in THF, gave (E)- and (Z)-α,α'-dimethoxystilbenes as the major products in most cases, the E:Z ratio of which varies from 0.4 to 5.0 depending upon the alkali-metal cation employed; the results are rationalized in the quasi-template effect in an acyclic system and the hard-soft ion principle.

Pd-catalyzed inter- and intramolecular carbene transfer from group 6 metal-carbene complexes

The use of group 6 metal-carbene complexes in inter- and intramolecular carbene transfer reactions has been studied. Thus, pentacarbonyl[(aryl)(methoxy)carbene]chromium(0) and tungsten complexes, 10, efficiently dimerize at room temperature in the presenc

Chemistry of O-Alkyl Selenoesters. Reaction with Triethylphosphine

The reaction between triethylphosphine and a number of aliphatic and aromatic selenoesters under oxygen-free conditions have been investigated.The purple intermediate formed in the reaction with the aliphatic selenoesters was quenched with atmospheric oxygen and gave the corresponding esters, whereas quenching with methyl iodide gave the corresponding 1-alkoxy-1-iodoalkyltriethylphosphonium iodides (13)-(16).The 1-alkoxy-1-iodoalkyltriethylphosphonium iodides gave the 1-alkoxyalkyltriethylphosphonium iodides (17)-(20) upon treatment with methanol, and treatment with benzaldehyde at -70 deg C gave α-alkoxyalkyl phenyl ketones (22)-(25).The reaction between the selenobenzoates and triethylphosphine gave α-dialkoxy-stilbenes and -dibenzyls.When the reaction was carried out in cyclohexene 7-alkoxy-7-phenylbicycloheptanes were formed.The presence of benzaldehyde in the reaction mixture led to α-alkoxystilbenes.An explanation for these different reactions is presented.
