Photochemistry of 3H-indazoles in protic media. Benzyl cations via protonation of 2-methylene-3,5-cyclohexadienylidenes

Photolysis of 3,3-disubstituted 3H-indazoles in protic media (ROH) gives rise to benzyl ethers, in addition to hydrocarbons (derivatives of benzocyclopropene, styrene, and fluorene) which are also found in aprotic solvents. In the presence of ROD, the benzyl ethers are formed with incorporation of deuterium into the ortho position, pointing to protonation of 2-methylene-3,5-cyclohexadienylidenes. Laser flash photolysis of 3H-indazoles generates diazo compounds and benzyl cations as transient intermediates.

Versatile and Convenient Lattice Hosts derived from Singly Bridged Triarylmethane Frameworks, X-Ray Crystal Structures of Three Inclusion Compounds

A new family of host molecules, based on the singly bridged triarylmethanol and triarylacetic acid frameworks, is described.These hosts form crystalline inclusions with a variety of uncharged organic molecules ranging from protic dipolar to apolar compounds (130 different species).The formation and stoicheiometry depend in a systematic manner on structural parameters of the host, such as the nature of the functional group and the substituents, and on the substituent positions.The crystal structures of three inclusion compounds have been studied by X-ray diffraction.They reveal the building principles of the new inclusion family.In the crystals of 1a*benzene (8:3), the benzene is interstitially entrapped by H-bonded tetramer clusters of 1a.Crystals of 1a*dioxane (4:3) are built of H-bonded 2:1 host-guest complexes including interstitial molecules of dioxane.In the case of 4c*EtOH (1:1), the building principle is formation of 2:2 host-guest clusters via a twelve-membered H-bonded ring.

REACTIONS OF N-SULFINYL-p-TOLUENESULFONAMIDE WITH ALCOHOLS

N-Sulfinyl-p-toluenesulfonamide (1) reacted with triaryl- and diarylmethanols to give predominantly N-substituted sulfonamides and SO2 presumably via carbonium ion intermediates.When carbonium ion forming alcohols, such as t-BuOH and Ph2C(Me)OH, were used, the predominant products were alkenes and p-toluenesulfonamide.Allylic alcohols afforded N-substituted sulfonamides, along with dienes and p-toluenesulfonamide.Alcohols wich could not predictably give relatively stable intermediate carbonium ions, gave either dialkyl sulfites or dialkyl ethers, along with p-toluenesulfonamide.In one case, namely with 9-phenylfluorenol, the 1:1 adduct with 1 (an amidosulfite) was isolated.A mechanism for the reaction is proposed.
