Abstract
Abstract Hydrides of nickel coordination compounds of the general formula HNi(MYZ)n X where M is P, As or Sb, Z is R or OR, where R is a hydrocarbyl radical of up to 18 carbon atoms or a hydrocarbyl radical of up to 18 carbon atoms substituted with any of -Cl, -Oor -CN, where Y is two Z''s or either -R''- or -O-R''-O-, where R''- is a divalent hydrocarbylene radical of from two to 12 carbon atoms, n is 3 or 4, and X is an anion of a protonic acid, particularly HSO4 , Cl , Br , Cn , CF3COO , AlCl4 , or ZnCl2CN or BF4 and the process of preparing these hydrides from the corresponding nickel complex and acid as well as the process of isomerizing 3-pentenenitrile to 4-pentenenitrile using the hydrides.
