Isolation and Structural Characterization of [P(AuPPh3)5][BF4]2 via Cleavage of a P−P Bond by Cationic Gold Fragments: Direct Evidence of the Structure of the Elusive Tetrakis[phosphineaurio(I)]phosphonium(+) Cation

“…These values are comparable to those seen in other clusters with aurophilic bonding. 3,[5][6][7][8] As a consequence of the gold-gold contacts, the basal Au-P-Au angles (74.4(1)°to 79.2(1)°) at the central phosphorus are contracted from ideal. The P-Au bonds between the central P and the basal gold atoms range from 2.356(3) to 2.379(3) Å.…”

A Reactivity-Driven Approach to the Discovery and Development of Gold-Catalyzed Organic Reactions

“…A subsequent survey of the literature led us to a report from 1974 describing the stoichiometric auration of b-keto esters (Scheme 1, part b). 7 Combining this report with Teles and co-workers' proposed mechanism led to the simple hypothesis that gold(I) complexes might be employed as catalysts for the addition of b-keto esters to alkynes, and this prompted us to investigate such goldcatalyzed additions.…”

P44.05: Data analysis of 993 subjects of fetal malformations from 1999 to 2006

“…Crucial information regarding the mechanism then came from attempts to recrystallize a [(Mes 3 P)AuX] catalyst from acetone. In this situation the carbonyl compound was present in high concentration, and a direct α‐auration was observed 18. Single crystals of [(Mes 3 P)AuCH 2 COCH 3 ] for a crystal structure analysis were obtained (Figure 1).…”
