Unusually Weak Metal−Hydrogen Bonds in HV(CO)4(P−P) and Their Effectiveness as H• Donors
摘要:
The V-H bonds in HV(CO)(4)(P-P) are unusually weak (55 to 58 kcal/mol). They transfer H center dot to styrene more rapidly than CpCr (CO)(3)H does and are effective stoichiometric reagents for the cyclization of appropriate 1,6-dienes.
