The development of effective methods to make new compounds represents a fundamental foundation in the discovery of materials exhibiting new properties that have potential everyday use in society. The emerging importance of the pnictogen (Pn) elements [phosphorus (P), arsenic (As), antimony (Sb) and bismuth (Bi)] in the discovery of new materials has prompted the development of new versatile methods to make new compounds of these elements. A number of polymers (plastics) featuring the pnictogen elements in the polymer chain have utility as new flame retardants, elastomers and antimicrobial agents. The Burford NSERC Discovery Grant supports the discovery of new compounds featuring chemical bonds between the pnictogen elements and the development of new methods to study the chemistry of these compounds. The results reported by this research group are changing the way in which chemists understand the chemistry of the pnictogen elements and other elements in general. Compounds containing P-P bonds, called phosphinophosphonium salts, exhibit enhanced stability and the preparative methods have been extrapolated to the other pnictogen elements to realise key milestones in the systematic and rational discovery and development of new series of compounds containing Pn-Pn bonds. The proposal describes approaches to evolve reactions that form Pn-Pn, Pn-Pn' and Pn-E bonds (E = elements Ge, Sn, Al, Ga, In), and to discover compounds representing new molecular frameworks, including polymeric Pn-Pn and Pn-E backbones. Members of the Burford research group are trained in experimental synthetic chemistry involving comprehensive characterization for compound identification and assessment of relative stability of particular new molecular frameworks. Since 2004, 10 undergraduate research students supervised by Burford have entered graduate schools in Canada, and 3 graduate students supervised by Burford now hold a faculty position.

制造新化合物的有效方法的开发代表了发现展示新特性的材料的基本基础，这些材料可能会在社会中日常使用。在发现新材料中，PNICTEGON（PN）元素（PN）元素[Phosphorus（p），砷（AS），武器（AS），锑（SB）和需要这些元素。 许多聚合物（塑料）包含聚合物链中的PNICTEGON元素，具有新的阻燃剂，弹性体和抗菌剂。 Burford Nserc Discovery Grant支持发现新化合物，这些化合物在PNICTEGON元件和开发新方法之间研究这些化合物的化学作用。该研究小组报道的结果正在改变化学家了解PNICTEGEN元素和其他元素的化学性质的方式。 含有P-P键的化合物（称为磷酸磷酸盐）表现出增强的稳定性，并且已经将制备方法推送到其他PNICTEGON元件上，以实现系统和合理发现和开发含有PN-PN键的新化合物的关键里程碑。 该提案描述了形成PN-PN，PN-PN'和PN-E键的反应的方法（E = Elements GE，SN，Al，Ga，in），并发现代表新分子框架的化合物，包括聚合PN-- PN和PN-E主干。 Burford研究小组的成员接受了实验合成化学的培训，涉及综合特征，以鉴定和评估特定新分子框架的相对稳定性。 自2004年以来，由伯福德（Burford）监督的10名本科研究学生在加拿大进入研究生院，而伯福德（Burford）监督的3名研究生现在担任教职员工职位。
