The diastereo- and enantioselective diboration of spirocyclobutenes provides a platform for the rapid preparation of a wide variety of chiral spirocyclic building blocks. The chemoselective functionalization of the carbon-boron bond in the products, including a stereospecific sp3-sp2 Suzuki–Miyaura cross-coupling reaction, provides a powerful tool to control the directionality and the nature of the exit vectors in the spirocyclic framework.
THE PHOTOELECTRON SPECTRA OF 4-METHYLENE THIACYCLOHEXANE DERIVATIVES THROUGH-BOND INTERACTION

The photoelectron spectra of 4-methylene thiacyclohexane, 4-difluoromethylene thiacyclohexane and trans-2-methylene-6-thiaperhydronaphthalene are described and compared with thiacyclohexane, difluoromethylene-cyclohexane and cis-2-methylene-6-thiaperhydronaphthalene.A through bond interaction between the sulphur lone pair and the vinyl-?-system is observed.The results are discussed in relation with the sigma-coupled transition observed in the electronic absorption spectra of the dicyano methylene derivatives by P.Pasman.
