Aromatic antimony compounds. Transition metal complexes of 2,5-dimethylstibacyclopentadienyl

Hydrostannation of 2,4-hexadiyne with dibutyltin dihydride gave 1,1-dibutyl-2,5-dimethylstannole, which was converted to 2,5-dimethylstibacymantrene and to bis(2,5-dimethylstibacyclopentadienyl)iron.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/23084/1/0000001.pd

The microwave spectrum, dipole moment and low frequency vibrational states for phosphabenzene

The microwave spectrum of the ground vibrational state and seven lowfrequency vibrational states for phosphabenzene (C5H5P) have been assigned. The small positive inertial defect and the alternation of intensities due to nuclear spin statistics for the ground state confirm a plannar structure with C2v symmetry. A PC bond distance of 1.70-1.73 A and 2 axis while one mode was symmetric. The dipole moment has been determined as 1.54+/-0.02 D.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/34207/1/0000496.pd

The preparation of (Z)-2-lithio-ortho-styryllithium via an ortho-directed lithiation

Lithiation of (Z)-2-lithiostyrene with t-butyllithium/TMEDA pentane led directly to (Z)-2-lithio-ortho-styryllithium. Subsequent treatment of this dilithio compound with difunctional electrophiles allowed the preparation of a variety of benzo[b]heteroles.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30439/1/0000062.pd

The exchange reaction of tetramethyl-diphosphine, -diarsine, -distibine and -dibismuthine

Tetramethyldiphosphine and tetramethyldiarsine undergo an exchange reaction to give (dimethylarsino)dimethylphosphine. The equilibrium constant at 25[deg]C in benzene is found to be 0.26. Similarly, mixtures of tetramethyldistibine with tetramethyldiarsine or tetramethyldibismuthine are partially converted to (dimethylarsino)dimethylstibine or (dimethylbismuthino)dimethylstibine, respectively. The thermochromic arsinostibine, 1-(2,5-dimethylarsolo)-2,5-dimethylstibole, has been prepared by a similar reaction.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26200/1/0000279.pd

The microwave spectrum, structure and nuclear quadrupole coupling constants for stibabenzene

The microwave spectrum of 121-SbC5H5, 123-SbC5H5, [beta]-dideutero 121-SbC5H3D2 and 123-SbC5H3D2 has been assigned in the region 26.5-40.0 GHz. The respective rotational constants and uncertainties are: A = 4512.69 +/- 0.42, B = 1738.00 +/- 0.01, C = 1254.51 +/- 0.01; A = 4512.84 +/- 0.30, B = 1729.80 +/- 0.01, C = 1250.22 +/- 0.01; A = 4176.18 +/- 0.33, B = 1660.94 +/- 0.01, C = 1188.15 +/- 0.01; A = 4176.60 +/- 0.61, B = 1652.94 +/- 0.03, C = 1184.03 +/- 0.03 (in MHz units). The structure is found to be planar, C2v in symmetry. The d(Sb-C) = 2.050 +/- 0.005 A and [angle]CSbC = 92.9[deg] +/- 1.0[deg]. The nuclear quadrupole coupling constants for the 121 and 123 antimony isotopes are [chi]aa = 456.4 +/- 4.1 MHz, [eta] = 0.396 +/- 0.008, and [chi]aa = 583.00 +/- 5.3 MHz, [eta] = 0.399 +/- 0.008, respectively. Several alternate techniques using the coupling constants as data support a [sigma]-donating property for antimony.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/22722/1/0000277.pd
