An ESR and MO study of the butatriene and tetramethylbutatriene radical cations

The radical cations of butatriene (BT+.) and tetramethylbutatriene (TMBT+.) have been stabilized in low-temperature halocarbon matrices studied by ESR spectroscopy.The spectra of BT+. and TMBT+. exhibit isotropic hyperfine splittings of 8.3 G (4H) and 13.0 G (12H), respectively.The skew angles of BT+. (25 deg) and TMBT+. (50 deg) are estimated by comparison the experimental hyperfine splittings with those obtained by semiempirical MO calculations.

Preparation of diadducts from dienes and dihalocarbenes. A general sonochemical method

Diadducts were formed in excellent yields from reactions of dienes with chloroform or bromoform, powdered sodium hydroxide and benzyltriethyl- ammonium chloride as catalyst using ultrasound.
