资源简介：
Treatment of [Re(dppm)3]I (dppm = PPh2CH2PPh2) with HCCPh produced the rhenium vinylidene complex ReI(CCHPh)(dppm)2. In the presence of HI, [Re(dppm)3]I reacted with HCCR (R = Ph, p-tolyl, C6H4-o-CHO, (CH2)5CH3) to give the rhenium carbyne complexes [ReI(CCH2R)(dppm)2]I and with HCCSiMe3 to give [ReI(CMe)(dppm)2]I. One-pot reactions of [Re(dppm)3]I, HCCC(OH)RR′ (RR′ = Ph2, Me2, PhMe), and HI produced the vinylcarbyne complexes [ReI(CCHCRR′)(dppm)2]I.
