The Chemical Structure, Dynamics, and Mechanisms - B Program of the Division of Chemistry supports Professor Dasan M. Thamattoor of Colby College, in an undergraduate-driven research program, to investigate alkylidenecarbenes generated from new photochemical sources based on cyclopropanated phenanthrene and indan systems. The program includes the study of acyclic alkylidenecarbenes with alkyl and aryl substituents, the investigation of cycloalkylidenecarbenes, with a particular emphasis on their ability to generate small- and medium-ring cycloalkynes, the study of dihalovinylidenes, and the domino generation of two alkylidenecarbenes from a single precursor and the formation of C2. This research program provides a research experience for undergraduate students, which trains them in the synthesis of organic molecules and in the physical methods used to characterize these molecules and determine their structures. The work will continue an outreach program that provides research opportunities to high school students over the summer months. Also, the implementation of new partnerships with math and science teachers at local elementary and middle schools, to deliver quality instruction in STEM subjects, will be sought and existing ones strengthened.

化学系的化学结构、动力学和机理-B项目支持科尔比学院的Dasan M. Thamattoor教授在本科生驱动的研究项目中研究基于环丙烷菲和茚满系统的新光化学源产生的亚烷基碳烯。该计划包括具有烷基和芳基取代基的无环亚烷基卡宾的研究、环亚烷基卡宾的研究，特别强调它们生成小环和中环环炔的能力、二卤代亚乙烯基的研究以及从多米诺骨牌生成两个亚烷基卡宾。单一前体和C2的形成。 该研究项目为本科生提供研究经验，训练他们合成有机分子以及用于表征这些分子并确定其结构的物理方法。 这项工作将继续开展一项外展计划，在夏季为高中生提供研究机会。此外，还将寻求与当地中小学的数学和科学教师建立新的合作伙伴关系，以提供 STEM 科目的高质量教学，并加强现有的合作伙伴关系。
