Abstract

The alkali metal reduction in vacuo of Ph 4Sn, Ph 6Sn 2, or Ph 3SnCl in tetrahydrofuran (THF) or 2-methyltetrahydrofuran (MTHF) solution proceeds stoichiometrically to yield Ph 3Sn −. The near UV photolysis at 93 K of rigid THF or MTHF glasses of Ph 3Sn − generates the Ph 3Sn radical. A g value of 1.998 ± 0.001, obtained from analysis of the electron spin resonance (ESR) spectrum, is compared with results reported in single crystal matrices and in gas phase condensations.
