Notes:
A variety of [Ru(CO)2L(η4enone)] complexes (L = phosphines, phosphites, and arsines, enone = (E)-4-phenylbut-3-en-2-one) have been synthesized. 1H-, 13C-, and 31P-NMR spectra are reported and the X-ray structures of two Ru complexes with L = Ph3P(7), Et3P (10) and one Fe complex with L = Ph3P (14) are presented. All three compounds crystallize in the same monoclinic space group P21/n with a = 10.575(2) Å, b =9.213(2) Å, and c = 27.608(5) Å, β = 100.04(2)°, Z = 4 for 7, a = 10.276(3) Å, b = 12.935(3) Å, and c = 14.854(2) Å, β = 96.96(2)°, Z = 4 for 10, and a = 10.492(2) Å, b = 9.232(3) Å, and c = 27.129(3) Å, β = 98.67(2)°, Z = 4 for 14. The structures of the Ru complexes are compared with the Fe analogues. In the case of M = Ru and L = (EtO)3P, (MeO)3P, and (i-PrO)3P (9, 11, and 13, respectively) stereoisomers could be detected by 31P-NMR at room temperature, wich arise from rotation at the coordinated metal centre.
