Abstract As a major product from the reaction of PNP-nitrite [P = P(C6H5)3] with elementary sulfur or a PNP-polysulfide (PNP)2S12 in acetone under anaerobic conditions PNP-perthionitrite (PNPnitrosodisulfide) PNP-SSNO has been isolated. VIS/UV-spectra point to a thionitrate or perthionitrate as a precursor. The structures of PNP-SSNO and of the product obtained on treating the perthionitrite with triphenylphosphane in acetonitrile, PNP -SNO (PNP-monothionitrite, PNP-nitrososulfide), have been elucidated through X-ray diffraction and independently from new chemical and NMRspectrometric arguments. PNP-SSN O crystallizes in the orthorhombic space group P ben with a = 11.843(3), b = 16.647(5), c = 15.556(4) Å , PNP -SNO in the triclinic group P1̄ with a = 10.525(3), b = 17.196(5), c = 9.451(3) Å , a = 95.22(3), β = 92.32(3), γ = 91.65(3)°.

The reactiono f8 with neat sodium was described to be the same as for 2.D uring the reactions of 8 with nitrogenous bases, the group observed at emperature increase of the reactionm ixture as well as the formation of crystalline and more air-stable products which were assigned to be addition products of the nitrogenous bases with 8 (Scheme 7).…”

In recent years, research in the fields of optoelectronics, anion sensors and bioimaginga gents have been greatly influenced by novel compounds containing triarylborane motifs. Such compounds possess an empty p-orbital at boron which resultsi nu seful optical and electronic properties. Such ad iversity of applications was not expected when the first triarylboranew as reported in 1885. Synthetic approaches to triarylboranes underwent variousc hanges over the following century,s ome of which are still used in the present day,s uch as the generally applicable routes developedb yK rause et al. in 1922developedb yK rause et al. in , or by Grisdale et al. in 1972 at Eastman Kodak. Some other developments were not pursued further after their initial reports, such as the synthesis of two triarylboranes bearing three different aromatic groups by Mikhailov et al. in 1958. This reviews ummarizes the developmento fs ynthetic approaches to triarylboranes from their first report nearly 135 years ago to the present.2021 The Authors.
