Synthesis of the ruthenaboratranes Ru(CS)(PPh3){B(mt)(3)} (Ru -> B)(8) and Ru(CO)(CNR){B(mt)(3)} (Ru -> B)(8) (mt = methimazolyl, R = Bu-t, C6H3Me2-2,6, C6H2Me3-2,4,6)

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.
