Half-sandwich rare-earth metal tris(alkyl) ate complexes catalyzed phosphaguanylation reaction of phosphines with carbodiimides: An efficient synthesis of phosphaguanidines
The phosphaguanylation reaction of phosphines with carbodiimides catalyzed by half-sandwich yttrium tris(trimethylsilylmethyl) ate complexes is achieved for the first time to efficiently prepare phosphaguanidines. The catalyst system of the yttrium ate complex displays better catalytic activity than those of neutral yttrium complexes.
