7440-31-5 Synthesis and structural characterization of carbons-adjacent stannacarboranes of the C2B10 system

-
The chemistry of p-block metallacarboranes of the C2B10 systems is largely unexplored in comparison with that of s-, d-, and f-block metallacarboranes. This article reports several carbons-adjacent stannacarboranes of the C2B10 system and their chemical properties for the first time. Reaction of SnCl2 with [{μ-1,2-[o-C6H4-(CH2)2]-1,2- C2B10H10}2Na4 (THF)6]n gave the Lewis base free stannacarborane {μ-1,2-[o-C6H4(CH2)2]-1,2- C2B10H10}-Sn (1). Recrystallization of 1 from MeCN, THF, and DME afforded the corresponding Lewis base coordinated stannacarboranes {μ-1,2-[o-C6H4 (CH2)2]-1,2-C2B10H10} Sn(MeCN) (2), {μ-1,2-[o-C6H4 (CH2)2]-1,2-C2B10H10}Sn (THF)·THF (3·THF), and {μ-1,2-[o-C6H4 (CH2)2]-1,2-C2B10H10}Sn (DME) (4), respectively. They were fully characterized by various spectroscopic data and elemental analyses. Complexes 2-4 were further confirmed by single-crystal X-ray analyses. https://www.lookchem.com/CASDataBase_7440-31-5.htm

1023-17-2 Syntheses, structures, and catalytic activity in Friedel–Crafts acylations of substituted tetramethylcyclopentadienyl molybdenum carbonyl complexes

-
Reactions of the substituted tetramethylcyclopentadienes [C 5 HMe 4 R] [R?=? t Bu, Ph, CH 2 CH 2 C(CH 3 ) 3 ] with Mo(CO) 3 (CH 3 CN) 3 in refluxing xylene gave a series of dinuclear molybdenum carbonyl complexes [(η 5 -C 5 Me 4 R)Mo(CO) 3 ] 2 [R?=? t Bu (1), Ph (2), CH 2 CH 2 C(CH 3 ) 3 (3)], [(η 5 -C 5 Me t Bu)Mo(μ-CO) 2 ] 2 (4)], and [(η 5 -C 5 Me 4 ) t Bu] 2 Mo 2 O 4 (μ-O) (5)], respectively. Complexes 1–5 were characterized by elemental analysis, IR, 1 H NMR, and 13 C NMR spectroscopy. In addition, their crystal structures were determined by X-ray crystal diffraction analysis. The catalytic activities of complexes 1–3 in Friedel–Crafts acylation in the presence of o-chloranil has also been investigated; the reactions were achieved under mild conditions to give the corresponding products in moderate yields. https://www.lookchem.com/CASDataBase_1023-17-2.htm

7440-47-3 Influence of pulse plating on the crystal structure and orientation of chromium

-
Chromium deposits with various structures and orientations were prepared by pulse plating from a sulfate-catalyzed chromic acid solution and without formic acid addition. The influences of the puls duration, off-time, curent density, formic acid concentration, and plating time on the structure and orientation were studied by X-Ray diffraction and transmition electron microcsopy. https://www.lookchem.com/CASDataBase_7440-47-3.htm
