Abstract:
The title phosphaarsenes (h5-C5H4R)Fe(CO)(PPh3)[As:PC6H2(CMe3)3-2,4,6] (R = H, Me; C5H5 = cyclopentadienyl) were formed in the reaction of (h5-C5H4R)Fe(CO)(PPh3)[As(SiMe3)2] with 2,4,6-(Me3C)3C6H2PCl2. Treating (h5-C5Me5)Fe(CO)2[As(SiMe3)2] with 2,4,6-Me3C6H2PCl2 gave the first transition-metal functionalized 1,3,2,4-diphosphadiarsetane I, which was characterized by x-ray crystallog.
