Access to Monomeric Lead(II) Hydrides with Remarkable Thermostability and Their Use in Catalytic Hydroboration of Carbonyl Derivatives.

We report on the remarkable stability of unprecedented, monomeric lead(II) hydrides (), where = 2,6-bis(3,5-diphenylpyrrolyl)pyridine and = (18-crown-6)potassium or ([2.2.2]-cryptand)potassium.
