1,3-Diborata-2,4-diphosphoniocyclobutane-1,3-diyls communicate through a para-phenylene linker.

چکیده
The presence of a second 1,3-diborata-2,4-diphosphoniocyclobutane-1,3-diyl in the para-position of a phenylene linker favors the diradical form over the 1,3-diborata-2,4-diphosphoniobicyclo[1.1.0]butane bond stretch isomer, as long as the two planar diradical units are coplanar with the linker. This demonstrates that two BPBP diradicals communicate through the phenyl ring.

Diverse reactions of sterically-protected 1,3-diphosphacyclobutane-2,4-diyls with hydride.
Hydride-induced elimination of resonance stabilized substituents from a phosphorus center of 1,3-diphosphacyclobutane-2,4-diyls leads to the formation of versatile cyclic phosphaallyl anions that are useful for the construction of various electrophile-modified biradical species.
متن کاملSubstituent effect on the energy barrier for σ-bond formation from π-single-bonded species, singlet 2,2-dialkoxycyclopentane-1,3-diyls
BACKGROUND Localized singlet diradicals are in general quite short-lived intermediates in processes involving homolytic bond-cleavage and formation reactions. In the past decade, long-lived singlet diradicals have been reported in cyclic systems such as cyclobutane-1,3-diyls and cyclopentane-1,3-diyls. Experimental investigation of the chemistry of singlet diradicals has become possible. The pr...
متن کاملPhotophysics of a poly„phenylenevinylene... with alternating meta-phenylene and para-phenylene rings
We have investigated the photophysics of the luminescent polymer poly~1,3-phenylenevinylene-alt-2,5dioctyloxy-1,4-phenylenevinylene! by a variety of optical spectroscopies. The incorporation of alternating meta-phenylene and para-phenylene rings restricts conjugation with respect to poly~para-phenylenevinylene! derivatives. As a consequence, excited states are blueshifted and the nonlinear susc...
متن کاملStudies on 1,1 ́-(4,6-dihydroxy-1,3-phenylene)diethanone based bischalcones and flavones
Resorcinol based bis-chalcones (2a-d) and flavones (3a-d) were synthesized and evaluated for their antimicrobial activity. Bis-chalcones (2a-d) were prepared by condensing 1,1 ́-(4,6-dihydroxy-1,3-phenylene)diethanone (1) with appropriate aryl-aldehydes, oxidative cyclization of bis-chalcones in presence of iodine gave corresponding flavones (3a-d). The synthesized compounds were evaluated for t...
