Nonreversible Enhanced Crystallization of Olefin Block Copolymer Induced by Preshearing

In this work, the influence of preshearing on crystallization of olefin block copolymer (OBC) was systematically investigated. It was found that upon an interval of melt preshear the crystallization rate of OBC was prominently elevated which was evidenced by both nonisothermal and isothermal crystallization results. The lamellar thickness of OBC increased and the size of spherulites decreased after shear. Interestingly, annealing and multiple heating and cooling experiments demonstrated that the enhancement effect on crystallization was nonreversible. The morphology observations suggested that preshearing caused an alteration in mesophase structure of OBC. On the basis of our results, we speculated that the increase in the amount of hard blocks that dissolved in the soft-block-rich matrix induced by shear promoted the unique “pass-through” crystallization process of OBC, which should be responsible for the largely enhanced crystallization of sheared OBC

[3 + 2]-Annulation of Prop-2-ynylsulfonium Salts: Access to Hydroindol-5-ones Containing a Methylthio Group

An unprecedented [3 + 2]-annulation of prop-2-ynylsulfonium salts and <i>p</i>-quinamines was developed, affording a series of hydroindol-5-ones with a methylthio group in moderate to good yields under mild conditions. In this reaction, the prop-2-ynylsulfonium salt acts as a novel C₂ synthon and sulfide does not serve as a leaving group, which provides facile access to organosulfur compouds

Sequential [1 + 4]- and [2 + 3]-Annulation of Prop-2-ynylsulfonium Salts: Access to Hexahydropyrrolo[3,2‑<i>b</i>]indoles

A powerful sequential [1 + 4]- and [2 + 3]-annulation has been developed using prop-2-ynylsulfonium salts and sulfonyl-protected <i>o</i>-amino aromatic aldimines, affording a series of hexahydropyrrolo­[3,2-<i>b</i>]­indoles in high yields. Prop-2-ynylsulfonium salts act as C₂ synthons in the reaction, and fused rings containing two five-membered azaheterocycles can be constructed in a single operation with readily accessible starting materials
