Thiolcarbonates pyrolyse more slowly than carbonates. Where the sulphur atom is attached to the group which will form the olefin, this difference amounts to three orders of magnitude; when the sulphur atom is in the other ether position it is only ten-fold. These rate changes are discussed in terms of similar substitutions in thioacetates.
硫代碳酸盐比碳酸盐更慢地热解。如果硫原子连接到将形成烯烃的基团上,则该差异为三个数量级;当硫原子在另一个醚位置时,它只有十倍。这些速率变化是根据硫代乙酸酯的类似取代进行讨论的。
