(OC) 5 ReFBF 3 (I) is obtained by abstraction of H - or CH 3 - from (OC) 5 ReH or (OC) 5 ReCH 3 , respectively, using Ph 3 CBF 4 . Treatment of I with water vapour yields the trifluorohydroxoborato complex (OC) 5 ReOHBF 3 (III). The reaction of I with σ and π-donors L proceeds to give the salts [(OC) 5 ReL] + BF 4 - (L (CH 3 ) 2 CO, CH 3 CN, CO, C 2 H 4 , propene, pentene-1) under mild conditions. [(OC) 5 ReC 2 H 4 ] + BF 4 - and Na + [Re(OC) 5 ] - form the ethylene bridged complex (OC) 5 CH 2 CH 2 Re(OC) 5 . |
