Contributions to the Chemistry of Boron, 131. A New Ring System of Boron: 1,4-Dimethyl-1,4-dithionia-2,5-diboratacyclohexane(CH3)3N · BH2CH2SCH3 (3) was prepared via Li[CH3SCH2BH3] (2). It reacts with CH3I to yield the sulfonium salt [(CH3)3N · BH2CH2S(CH3)2]I (4) and decomposes on heating to the title compound 8. The latter contains a six-membered ring in chair conformation and the methyl groups in equatorial positions as revealed by X-ray crystallography.
Notes:
Über Li[CH3SCH2BH3] (2) wurde (CH3)3N · BH2CH2SCH3 (3) dargestellt, das mit CH3I in das Sulfoniumsalz [(CH3)3N · BH2CH2S(CH3)2]I (4), bei der Thermolyse in die Titelverbindung 8 übergeht. Letztere enthält nach Röntgenstrukturanalyse einen Sechsring in Sesselkonformation mit äquatorial angeordneten Methylgruppen.
