Abstract
A novel bowl-type triarylgermyl group, tris(2,2″,6,6″-tetramethyl[1,1′:3′,1″-terphenyl]-5′-yl)germyl (denoted as TRMG), was designed, and a germanol and its derivatives bearing this framework were synthesized. X-ray crystallographic analysis of TRMG–OH (5) revealed that there is no OH···O hydrogen bonding between adjacent molecules, although the possible presence of a weak intermolecular OH···π interaction was suggested. In sharp contrast to organogermanols known so far, 5 is extremely resistant to self-condensation; no digermoxane was obtained when 5 was subjected to the conditions under which Ph3GeOH (8) affords the corresponding digermoxane. On the other hand, germanol 5 was readily converted to various derivatives. The crystal structure of TRMG–SH (12) was also determined.
