The reaction of [Ru(CH=CH2)Cl(CS)(PPh3)(2)] with Na[HB(mt)(3)] (mt = methimazolyl) provides the ruthenaboratrane [Ru(CS)(PPh3)B(mt)(3)}]. The reaction of [Ru(CO)(PPh3)B(mt)3}] with CO to provide [Ru(CO)(2)B(mt)(3)}] is reversible, while the phosphine-free ruthenaboratranes [Ru(CO)(CNR)B(mt(3))}] (R = Bu-t, C6H3Me2-2,6, C6H2Me3-2,4,6) form irreversibly upon addition of isonitriles (CNR) to [Ru(CO)(PPh3)B(mt)(3)}]. The crystal structures of the ruthenaboratranes [Ru(CS)(PPh3)B(mt)(3)}], [Ru(CO)((CNBu)-Bu-t)(B(mt)(3)}], and [Ru(CO)(CNC6H2Me3-2,4,6)B(mt)(3)}] are reported.
