“…In contrast divalent organolead compounds are relatively rare and their chemistry is poorly explored. 298,299 The organoplumbylene chemistry has been restricted mostly around the first well-characterized organolead(II) compounds Pb(Z 5 -C 5 H 5 ) 2 and Pb[CH(SiMe 3 ) 2 ] 2 [302][303][304] But relatively little is known about the chemistry of smaller heteroleptic organoplumbylene derivatives, and studies in this area have been emerging in recent years. 296,[305][306][307] In 2009 we reported the preparation and characterization of a number of organoplumbylene compounds LPb(Me) (115), LPb(Ph) (116), and LPb(CCPh) (117).…”

Interstellar molecules: guides for new chemistry

Interstellar space is among the most remarkable chemical laboratories in the universe. The existence of many unstable species with low-valent main group elements in the interstellar medium inspired us to investigate the feasibility of laboratory synthesis of such unstable molecules. Particularly the lighter Group 14 element carbon plays a very important role in space astrochemistry. Low-valent carbon as well as silicon were detected in the interstellar environment. This article describes our recent efforts in developing amazing chemistry of heavier low-valent Group 14 elements. This study unravels that the disproportionation pathway of the low-valent Group 14 elements can be arrested by using a sterically protected ligand, then one can artificially generate the situation observed in the interstellar surrounding where the chance of disproportionation is very low as the molecules are extremely dilute.

“…The metal atoms and carbonyls of the two molecules in the asymmetric unit were refined with anisotropic thermal parameters using the SHELX 7635 program, and refining on F (R' = 0.0766). The geometry of the phenyl rings was constrained and all the hydrogens were placed geometrically, with common thermal parameters given to those in similar environments [phenyl CH, 0.16(2); ligand CH, 0.068 (7); CH, of each ligand, 0.15( I), 0.14( l), 0.16( l), 0.22( 1) A2]. The highest peaks in the final difference map were 0.86 e k3, in the vicinity of the tin atoms.…”

Reactions of [Fe,(CO) ,] with diaryltin species SnR, (R ' = 2,4,6-triisopropylphenyl, R2 = 2,6-diethylphenyl, R3 = pentamethylphenyl) and with Sn[CH(PPh,),], have been investigated. The tin reagents SnR, (R = R' or R2) reacted under mild conditions to give in moderate yields the trinuclear species [Fe,(C0)8(p-SnR1,)] 1 or [Fez( CO),(p-SnR2,)] 2, as orange-red crystalline solids, which decompose in air on prolonged exposure. The compound [Fe2(CO),(p-SnR4,)] 3 (R4 = 2,4,6-triphenylphenyl) can be similarly obtained. Prolonged treatment of the carbonyl with the novel tin reagent SnR3,, by contrast, afforded the known compound spiro-[(OC),Fe,SnFe,(CO),] 4 for which data are briefly reported. Reactions with tin or lead reagents M[CH(PPh,),], (M = Sn or Pb) afforded [Fe2(co),(p-co)(p-dppm)] [dppm = 1,2bis(diphenylphosphino)methane] rapidly and almost quantitatively. Full crystal and molecular structural data are reported for [Fe,(CO),(p-SnR',)] and [Fe2(CO),(p-SnR2,)]. Mossbauer data are also presented for compounds 1-3, and interpreted in terms of the structural data for these and other systems.

“…Recently, we have reported on our interest in divalent compounds of Ge, Sn and Pb as components of mixed-metal clusters. [23][24][25][26][27] For example, [Ru(CO) 12 ] was shown to react at low temperatures with SnR 2 (R = C 6 H 2 Pr i 3 -2,4,6), or at higher temperatures with its corresponding cyclic trimer, [(SnR 2 ) 3 ], 28 to give both [Ru 3 (CO) 10 (µ-SnR 2 ) 2 ] and [Ru 3 (CO) 9 (µ-SnR 2 ) 3 ]. 27 Furthermore, reaction of the pentametallic species [Ru 3 (CO) 10 (µ-SnL 2 ) 2 ] [L = RЈ = CH(SiMe 3 ) 2 or R] with SnRЈ 2 or SnR 2 afforded the hexametallic clusters [Ru 3 (CO) 9 (µ-SnRЈ 2 ) n (µ-SnR 2 ) 3 Ϫ n ] (n = 1 or 2): in the reaction of [Ru 3 (CO) 12 ] with SnRЈ 2 the hexametallic cluster [Ru 3 (CO) 9 (µ-SnRЈ 2 ) 3 ] was isolated in addition to the previously reported Ru 3 Sn 2 cluster.…”
