资源简介:
The discovery of cycloosmathioborane compounds is reported. These species, which are prepared by the simultaneous dehydrogenation of a trihydride hydrogensulfide osmium(IV) complex and a BH3NHR2 amine–borane, bear an Os–S–B three-membered ring, being a manifestation of the 4n + 2 Hückel aromaticity in which n = 0 and where the two π electrons of the ring are provided by the S atom.
