Connector vs. Adjunct

Doesn't an infinitive phrase placed at the beginning of a sentence anaphoric to something mentioned previously in the discourse make it a connective (sentence connector)?

Example:

He wants to be a singer. To achieve this goal, he is working very hard.

Here "To achieve this goal" can be said to be a sentence connector.  Otherwise, it will be only a purpose adjunct, which can be placed at the end of the sentence.

Can "To achieve this goal"/"to this end" be called sentence connectors?

Solution 1:

The to-infinitival examples given are both simply adjuncts of purpose. They are linked to the preceding text anaphorically by this. They are interpreted roughly as:

To achieve this goal (of being a singer), he is working very hard.

Connective adjuncts that also serve to mark a semantic relationship (other than ordering, addition and comparison, elaboration and exemplification or informational status) between the clause they introduce and the preceding text are called impure connectives (CaGEL p777-779). They don't have any elements that anaphorically link to the preceding text. Examples for those that show purpose are: accordingly, as a result, consequently, hence, in consequence, so, therefore, thus.
