Unusually weak metal-hydrogen bonds in HV(CO)(4)(P-P) and their effectiveness as H-center dot donors
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.
