  Syntheses of carbene and alkenyl derivatives of palladium. Solid-state structures of {(Me2NCS2) Pd(PEt3) [η1−C(N(CH3) C(CH3)3) CH3]}BPh4 and {(Me2NCS2)Pd(PEt3)[η1−C(NHC(CH3)3)CH3]}PF6 · Et2O

  摘要：

  The reaction of (t)BuNC and (Me(2)NCS(2))Pd(PEt(3))CH3 yields (Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(NC(CH3)(3)CH3]. Reaction of this amino acyl complex with [(CH3)(3))]BF4 yields, after anion exchange, {Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(NHC(CH3)(3)CH3]}BPh(4). An analogous reaction with NH4PF6 yields {(Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(NHC(CH3)(3)CH3]}PF6. Both of these carbene complexes have been characterized crystallographically. Crystal data: {(Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(N(CH3)C(CH3)(3))CH3]}BPh(4) triclinic, P (1) over bar, a = 12.253(12) Angstrom, b = 14.422(5) Angstrom, c = 11.564(5) Angstrom, alpha = 97.83(3)degrees, beta = 93.04(6)degrees, gamma = 85.21(5)degrees, V = 2018 Angstrom(3), Z = 2, T = 298 K, R(F) = 7.6%; {(Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(NHC(CH3)(3))CH3]}PF6 . Et(2)O triclinic, P (1) over bar, a = 12.844(2) Angstrom, b = 15.247(2) Angstrom, c = 8.312(2) Angstrom, alpha = 105.60(1)degrees, beta = 101.67(2)degrees, gamma = 90.20(1)degrees, V = 1533 Angstrom(3), Z = 2, T = 298 K, R(F) = 5.4%. In both complexes, the overall coordination geometry is approximately planar about both the palladium atom and carbene carbon atom, and these two planes are perpendicular. Reaction of {(Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(N(CH3)C(CH3)(3))CH3]}BPh(4) with LiCH3 results in deprotonation at the beta-carbon yielding (Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(N(CH3)C(CH3)(3))-CH2], and this reaction is reversed with HBF4 . Et(2)O. The reaction of LiC(OCH2CH3)=CH2 with (Me(2)NCS(2))Pd(PEt(3))Cl yields (Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(OCH2CH3)=CH2]. This alkenyl complex reacts with BH3 in ethanol to yield (Me(2)NCS(2))Pd(PEt(3))[eta(1)-CH(OCH2CH3)CH3]. (Me(2)NCS(2))Pd(PEt(3))[eta(1)-C(OCH2CH3)=CH2] also forms in the reaction of (Me(2)NCS(2))Pd(PEt(3))H and HC=COCH2CH3, along with both geometric isomers of (Me(2)NCS(2))Pd(PEt(3))[eta(1)-CH=CH(OCH2CH3)]. Reaction of phenylacetylene and (Me(2)NCS(2))Pd(PEt(3))H yields mainly (Me(2)NCS(2))Pd(PEt(3)){eta(1)-C(Ph)=CH2) with small amounts of one of the other regioisomers present.
