CF 3–Ph reductive elimination from [(Xantphos)Pd(Ph)(CF 3)] ( 1) and [( i-Pr-Xantphos)Pd(Ph)(CF 3)] ( 2) has been studied by experimental and computational methods. Complex 1 is cis in the solid state and predominantly cis in solution, undergoing degenerate cis–cis isomerization (Δ G ≠ exp = 13.4 kcal mol –1; Δ G ≠ calc = 12.8 kcal mol –1 in toluene) and slower cis–trans isomerization ( Δ G calc = +0.9 kcal mol –1; Δ G ≠ calc = 21.9 kcal mol –1). In contrast, 2 is only trans in both solution and the solid state with trans-2 computed to be 10.2 kcal mol –1 lower in energy than cis-2.

Kinetic and computational studies of the previously communicated ( J. 2006, 128, 12644), remarkably facile CF 3–Ph reductive elimination from 1 suggest that the process does not require P–Pd bond dissociation but rather occurs directly from cis-1. The experimentally determined activation parameters (Δ H ≠ = 25.9 ± 2.6 kcal mol –1; Δ S ≠ = 6.4 ± 7.8 e.u.) are in excellent agreement with the computed data (Δ H ≠ calc = 24.8 kcal mol –1; Δ G ≠ calc = 25.0 kcal mol –1).

Δ G ≠ calc for CF 3–Ph reductive elimination from cis-2 is only 24.0 kcal mol –1; however, the overall barrier relative to trans-2 is much higher (Δ G ≠ calc = 34.2 kcal mol –1) due to the need to include the energetic cost of trans–cis isomerization. This is consistent with the higher thermal stability of 2 that decomposes to PhCF 3 only at 100 °C and even then only in a sluggish and less selective manner. The presence of excess Xantphos has a minor decelerating effect on the decomposition of 1. A steady slight decrease in k obs in the presence of 1 and 2 equiv of Xantphos then plateaus at [Xantphos]: 1 = 5, 10, and 20. Specific molecular interactions between 1 and Xantphos are not involved in this kinetic effect (NMR, T 1 measurements). A deduced kinetic scheme accounting for the influence of extra Xantphos involves the formation of cis-[(η 1-Xantphos) 2Pd(Ph)(CF 3)] that, by computation, is predicted to access reductive elimination of CF 3–Ph with Δ G ≠ calc = 22.8 kcal mol –1.

Contents • • • • • • Biography Marretje Leenderts de Grauw was born probably in Amsterdam, Noord-Holland, Netherlands. Marretje died after 4 November 1668 in New York. She was the daughter of Leendert Arentsen de Gra(e)uw, who was probably born in Aalsmeer, Noord-Holland, Netherlands, and of Leuntje Alberts L(e)ydecker, born in Amsterdam. Marretje was married to about 1637, probably near Amsterdam. After Leendert Arentsen died, his land was conferred to Barent Jacobsen, 'one daughter being the wife of Barent Jacobsen.' The De Graeuw family immigrated to America in 1638 in the ship Dolphin. All the children of Barent Kool and Marretje Leendertse De Graeuw were born in New Amsterdam (New York City).

Marretje and Barent had at least nine children; some sources name ten children. The baptisms of eight of Barent and Marretje's children from 1640 through 1657 were recorded at the New Amsterdam Dutch Reformed Church, the records of which date only from 1639.
