《Experimental and computational studies on a three-membered diphosphido thorium metallaheterocycle [η5-1,3-(Me3C)2C5H3]2Th[η2-P2(2,4,6-iPr3C6H2)2]》 was written by Zhang, Congcong; Wang, Yongsong; Hou, Guohua; Ding, Wanjian; Zi, Guofu; Walter, Marc D.. SDS of cas: 882-33-7This research focused onthree membered diphosphido thorium metallaheterocycle preparation crystal mol structure; reactivity three membered diphosphido thorium metallaheterocycle; tert butyl cyclopentadienyl thorium diphosphido metallaheterocycle preparation crystal structure. The article conveys some information:
A three-membered thorium metallaheterocycle [η5-1,3-(Me3C)2C5H3]2Th[η2-P2(2,4,6-iPr3C6H2)2] (4) is readily prepared besides H2 from [η5-1,3-(Me3C)2C5H3]2Th(PH-2,4,6-iPr3C6H2)2 (3) upon heating in toluene solution D. functional theory (DFT) studies were performed to elucidate the 5f orbital contribution to the bonding within Th-(η2-P-P) revealing more covalent bonds between the [η5-1,3-(Me3C)2C5H3]2Th2+ and [η2-P2(2,4,6-iPr3C6H2)2]2- fragments than those in the related thorium metallacyclopropene. Consequently, distinctively different reactivity patterns emerge, e.g., while 4 reacts with pyridine derivatives such as 4-dimethyaminopyridnie (DMAP) and forms the DMAP adduct [η5-1,3-(Me3C)2C5H3]2Th[η2-P2(2,4,6-iPr3C6H2)2](DMAP) (5), it may also act as a [η5-1,3-(Me3C)2C5H3]2Th(II) synthon when reacted with bipy, Ph2S2 or Ph2Se2. Nevertheless, no reaction of complex 4 with alkynes is observed, but it reacts as a nucleophile towards nitriles and aldehydes resulting in five- or seven-membered metallaheterocycles, resp. DFT computations provide some addnl. insights into the exptl. observations. The results came from multiple reactions, including the reaction of 1,2-Diphenyldisulfane(cas: 882-33-7SDS of cas: 882-33-7)
1,2-Diphenyldisulfane(cas: 882-33-7) belongs to ethers.Oxygen is more electronegative than carbon, thus the alpha hydrogens of ethers are more acidic than those of simple hydrocarbons. They are far less acidic than alpha hydrogens of carbonyl groups (such as in ketones or aldehydes), however. SDS of cas: 882-33-7
