1-Iodo-1-selenoalkenes as versatile alkene 1,1-dianion equivalents. Novel connective approach towards the tetrahydropyran subunit of polycavernoside A

syn-Hydroalumination of 2,4,6-triisopropylphenylselanyl-1-alkynes with DIBAL-H followed by Al/I exchange with I2 afforded exclusively (E)-1-iodo-1-selenoalkenes in good yields. 1-Iodo-1-selenopropene 10 proved to be a convenient 1,1 dianion equivalent, leading to the stereodivergent synthesis of allylsilanes (Z)-6 and (E)-6. Adduct 3, an intermediate in the synthesis of the tetrahydropyran subunit of polycavernoside A, was efficiently synthesised from allylsilane (Z)-6 and aldehyde 7 via an intramolecular Sakurai cyclisation.

Stereoselective synthesis of (E)-1-iodo-1-selenoalkenes via hydroalumination-iodination of 1-alkynyl selenides

syn-Hydroalumination of 2,4,6-triisopropylphenylselanyl-1-alkynes 22 with DIBAL-H, followed by Al/I exchange with I2, afforded selectively the corresponding (E)-1-iodo-1-selenoalkenes in good yields. The sterically hindered 2,4,6-triisopropylphenyl group proved to be mandatory and prevented the formation of undesired by-products.

NEW STERICALLY CONGESTED ORGANOSELENIUM AND TELLURIUM COMPOUNDS

The report on recent preparative, n.m.r. spectroscopic and structural results concerning steric effects in organoselenium and -tellurium chemistry covers: 1. extremely bulky ditellurides and diselenides, including rotational barriers and unusual conformat

Sterically Hindered Thiolato, Selenolato and Tellurolato Complexes of Mercury(II)

Mercury(II) complexes of sterically demanding arenechalcogenolato ligands, Hg(EC6H2-2,4,6)2 (E = S or Se; R = Me, Pri or But: E = Te; R = Me or Pri) have been prepared.Whereas complexes carrying smaller aryl substituents (R = Me) are polymeric, those with R = Pri and But form linear two-co-ordinate molecules.For a given R, the volatility of the complexes increases for E = S Pri >> But.

Protolysis of M2 (M = Zn or Cd) with arenechalcogenols 2,4,6-R3C6H2EH (E = S or Se; R = Me, Pri or But) gives the corresponding chalcogenolato complexes M(EC6H2R3-2,4,6)2 in high yield.Complexes with R = Me form co-ordinat
