sample of this mixture could identify the unstable bis-selenium(IV)
trifluoride biphen(SeF3)2.
19F NMR (CH2Cl2): δ = 6.4 (br., Fax: ), –73.6 (br., Feq). 77Se NMR
(CH2Cl2): δ = 1154 (br). Further unidentified resonance after few hours
at 25 °C: 77Se NMR (CH2Cl2): δ = 1072.

Reaction of biphenSe2 (2) with SO2Cl2: Into a solution of 2
(0.4 mmol) in dichloromethane (5 mL) sulfuryl chloride (1.45 mmol)
was added dropwise at 0 °C and the mixture was stirred 30 min at this
temperature. The yellowish mixture was concentrated to 1 mL volume
in vacuo and examined by NMR spectroscopy. Identified were 1,
Se2Cl2, 4 (all by 77Se NMR resonance) and SeCl4 (Raman).

Reaction of biphenSe2 (2) with Br2: Into a solution 2 (2.0 mmol) in
dichloromethane (10 mL) bromine (14.5 mmol) was added dropwise
at 0 °C. After approximately 30 min an orange colored solid precipi-
tated, which was separated and washed with CCl4, and identified by
77Se NMR spectroscopy as 5. In the reaction solution 1 was detected
by 77Se NMR spectroscopy.

Dibenzo[1,2]diselenine-iodine (7): Into a solution of 2 (0.5 mmol) in
dichloromethane (8 mL) iodine (1.5 mmol) was added at 25 °C. After
stirring the deep red solution for an hour, all volatile materials were
removed in vacuo. The deep red solid (60 % yield) was identified via
X-ray crystallography as the iodine adduct biphenSe2·I2 (7).
