• Type system in programming languages

  Type system provides a precise description of a programming language. This is a prerequisite for the implementation and use of language. It also conducts mechanical and transparent type-checking on programs to prevent the occurrence of execution error during the running of programs. So, it can be said that, on the one hand, type system works as a formal tool to do mathematical analysis of language; on

  类型系统提供了对编程语言的精确描述。这是实现和使用语言的先决条件。它还对程序进行机械透明的类型检查，以防止程序运行过程中出现执行错误。所以，可以说，一方面，类型系统作为一种形式化的工具来进行语言的数学分析；另一方面，它是一种严格而精确地设计和实现语言的形式化方法。在本文中，首先讨论了类型系统的一些基本概念。然后，详细给出了基于图重写的函数式语言——SClean 的类型系统的实现。希望所提出的使用和实现类型系统的方法具有实用价值。

• Acyl radicals: intermolecular and intramolecular alkene addition reactions
  作者：Dale L. Boger、Robert J. Mathvink

  DOI：10.1021/jo00031a021

  日期：1992.2

  A full study of the use of phenyl selenoesters as precursors to acyl radicals and their subsequent participation in intermolecular and intramolecular alkene addition reactions is detailed. Primary alkyl-, vinyl-, and aryl-substituted acyl radicals generated by Bu3SnH treatment of the corresponding phenyl selenoesters participate cleanly in intermolecular addition reactions with alkenes bearing electron-withdrawing or radical-stabilizing substituents at rates that exceed those of the potentially competitive decarbonylation or reduction. Similarly, their intramolecular addition to activated or unactivated alkenes proceeds without significant competitive reduction or decarbonylation and at rates generally greater-than-or-equal-to 1 x 10(6) s-1 with some occurring at rates greater-than-or-equal-to 3 x 10(7) s-1. Consistent with their behavior in intermolecular addition reactions, the 5-exo-trig cyclizations of secondary and tertiary alkyl-substituted acyl radicals to an unactivated olefin acceptor may be accompanied by varying degrees of decarbonylation, even under low-temperature free-radical reaction conditions. Studies are presented which suggest that the intramolecular additions of acyl radicals to alkenes under the conditions detailed herein may be regarded as irreversible, kinetically controlled processes which exhibit regioselectivity that is predictable based on well-established empirical rules set forth for the analogous free-radical cyclization reactions of alkyl radicals.
